In a child with an age of 12 months – pincer grasp should be well developed. It is essential to have a good grasp of important milestones. Most 12-month-old children will be mobile, by standing holding onto a support, lifting one foot and moving it sideways (‘cruising’ around the furniture). They will demonstrate a neat pincer grasp, e.g. picking up a raisin or piece of paper between the tip of the index finger and the thumb. Words (or meaningful word-like utterances) are produced, but words are not usually chosen and put together deliberately by a child until after the second birthday (typically around the age of 30 months). Word combinations used earlier than this are likely to be an echo of a learnt phrase which may be understood by the child to be one single word even though they are a combination of more than one word (e.g. daddy, home). Building a tower of three cubes and following a one-step command such as ‘take off your socks’, is expected at 18 months.

The Moro reflex is a normal primitive, infantile reflex. It can be seen as early as 25 weeks postconceptional age and usually is present by 30 weeks postconceptional age.6 month old milestones:Social and Emotional:Knows familiar faces and begins to know if someone is a stranger Likes to play with others, especially parents Responds to other people’s emotions and often seems happy Likes to look at self in a mirror Language/Communication:Responds to sounds by making sounds Strings vowels together when babbling (ah,ť eh,ť ohť) and likes taking turns with parent while making sounds Responds to own name Makes sounds to show joy and displeasure Begins to say consonant sounds (jabbering with m,ť bť) Cognitive (learning, thinking, problem-solving):Looks around at things nearby Brings things to mouth Shows curiosity about things and tries to get things that are out of reach Begins to pass things from one hand to the other Movement/Physical Development:Rolls over in both directions (front to back, back to front) Begins to sit without support When standing, supports weight on legs and might bounce Rocks back and forth, sometimes crawling backwards before moving forward

Jacob is likely to be four years old as demonstrated by his activities throughout the day. Most 4 year olds are able to run well, jump and hop, but find skipping a little more difficult. They are able to brush their teeth and dress themselves with supervision, and go to the toilet alone.

18-month-old milestonesSocial and EmotionalLikes to hand things to others as play May have temper tantrums May be afraid of strangers Shows affection to familiar people Plays simple pretend, such as feeding a doll May cling to caregivers in new situations Points to show others something interesting Explores alone but with parent close by Language/CommunicationSays several single words Says and shakes head noť Points to show someone what he wants Cognitive (learning, thinking, problem-solving)Knows what ordinary things are for; for example, telephone, brush, spoon Points to get the attention of others Shows interest in a doll or stuffed animal by pretending to feed Points to one body part Scribbles on his own Can follow 1-step verbal commands without any gestures; for example, sits when you say sit downť Movement/Physical DevelopmentWalks alone May walk up steps and run Pulls toys while walking Can help undress herself Drinks from a cup Eats with a spoon

By the age of three months a child should become more fascinated with their hands and fingers; they can bring their hand to their mouth, open and close their hand, and shake and grab at dangling objects and toys. Their ability to roll over will come by the time the child is 6 months, at which time they will also be able to sit with support. Soon, at 8-9 months, attempts will be made to crawl and as they approach 12 months they will be able to pull on objects to stand.

PARACHUTE REFLEX This reflex occurs in slightly older infants when the child is held upright and the baby’s body is rotated quickly to face forward (as in falling). The baby will extend his arms forward as if to break a fall, even though this reflex appears long before the baby walks.Newborn reflexes are:Rooting reflex:This reflex starts when the corner of the baby’s mouth is stroked or touched. The baby will turn his or her head and open his or her mouth to follow and root in the direction of the stroking. This helps the baby find the breast or bottle to start feeding. This reflex lasts about 4 months.Suck reflex:Moro reflex:The Moro reflex is often called a startle reflex. That’s because it usually occurs when a baby is startled by a loud sound or movement. In response to the sound, the baby throws back his or her head, extends out his or her arms and legs, cries, then pulls the arms and legs back in. This reflex lasts until the baby is about 2 months old.Tonic neck reflex:When a baby’s head is turned to one side, the arm on that side stretches out and the opposite arm bends up at the elbow. This is often called the fencing position. This reflex lasts until the baby is about 5 to 7 months old.Grasp reflex:Stroking the palm of a baby’s hand causes the baby to close his or her fingers in a grasp. The grasp reflex lasts until the baby is about 5 to 6 months old. A similar reflex in the toes lasts until 9 to 12 months.Stepping reflex:This reflex is also called the walking or dance reflex because a baby appears to take steps or dance when held upright with his or her feet touching a solid surface. This reflex lasts about 2 months.

By 15 months, it’s common for many toddlers to:- say three to five words.- understand and follow simple commands.- point to one body part.- walk alone and begin to run.- climb on furniture.- make marks with a crayon.- imitate activities, such as housework.

Among the provided options, we would expect a normally developing six-month-old child to have lost Moro’s reflex.Note:The Moro reflex is present from birth and persists until 4 months of age. It is abnormal for the Moro reflex to persist much beyond this stage, and if it does, cerebral palsy should be considered.A normal 6-month old baby should be able to roll over from front to back, readily follow objects with their eyes, transfer objects from hand to hand, recognise parental voices and babble and laugh.Other options:- Having a pincer grip is more typical of a 9-12-month-old.- Although at 6 months babies are often able to sit briefly or with support, sitting steadily is typically seen at 9 months.- Starting to stand with support is more typical of a 9-12-month-old.- Waving bye-bye is more typical of a 9-12-month-old.

All the given development milestones are compatible with the given age.

Among the options provided, a 1-year-old child will be able to understand object permanence e.g. understands that objects continue to exist even when they can’t be seen, e.g. looking for a fallen toy.At the age of 1 year, children should have developed an accurate pincer grip and be able to see and co-ordinate and manipulate fairly small objects such as a raisin.Gross motor development varies, but the average 1-year-old should be able to stand and cruise around furniture or walk with their hands held but not necessarily walk unaided.Drinking from a cup will become established at around 15 months and scribbling at 18 months.

Not being able to form a sentence at the age of 18 months is quite normal. A combination of two words to form a sentence can be done by 2 years of age.

Fine motor development involves greater use of the hands to perform more precise tasks. By 6 -12 months children should be able to reach for small objects and pass an object from one hand to the other. From 1 -2 years they can perform more complex tasks such a building a tower of blocks, feeding themselves, and turning knobs. In terms of pencil skills, they should be able to imitate scribbles and then spontaneously scribble. By the age of 2 years they can draw a line, and by three they can draw a circle. From the age of 3.5 they can draw a cross, 4.5 – a square, 5 – a triangle, and 6 a diamond.

Language/Communication milestones of 2 years old:Points to things or pictures when they are named Knows names of familiar people and body parts Says sentences with 2 to 4 words Follows simple instructions Repeats words overheard in conversation Points to things in a book

In the first few years of life the developing sensory inputs are important. Hearing is essential for speech and language development and may be delayed when a child cannot hear. Therefore any child with a family history of hereditary deafness should be screened. From about 4-6months babies are able to laugh and babble when excited or unhappy. By the age of 9 months the child should be able to bring together groups of same sound syllables and be able to say one or two words by the 1st birthday. If a child is unable to babble by 10-12 years, it may indicate hearing impairment. By the age of 2 a child should be able to speak in 1 or 2 word phrases and often repeats phrases used by others, known as Echolalia.

Among the options provided, an 8-week-old full-term infant with normal developmental milestones will smile in response to appropriate stimuli.Rationale:Smiles in response to appropriate stimuli are seen from around 6 weeks of age. A social smile, where the infant has an awareness that a smile attracts attention, is not observed until around 3 months of age.Other options:- At 6 weeks an infant is able to follow objects in the horizontal plane through 90 deg; fixing and following an object through 180 deg in the horizontal plane is a milestone achieved at 3 months, as is pushing up onto forearms. – Pushing up onto hands occurs by around 5 months.- Infants of 3 months should startle to a 60 dB sound.

3-year-old milestones:Social and Emotional:- Copies adults and friends – Shows affection for friends without prompting – Takes turns in games – Shows concern for crying friend – Understands the idea of mineť and hisť or hersť – Shows a wide range of emotions – Separates easily from mom and dad – May get upset with major changes in routine- Dresses and undresses self Language/Communication- Follows instructions with 2 or 3 steps – Can name most familiar things – Understands words like in,ť on,ť and underť – Says first name, age, and sex- Names a friend – Says words like I,ť me,ť we,ť and youť and some plurals (cars, dogs, cats) – Talks well enough for strangers to understand most of the time – Carries on a conversation using 2 to 3 sentencesCognitive (learning, thinking, problem-solving)- Can work toys with buttons, levers, and moving parts – Plays make-believe with dolls, animals, and people – Does puzzles with 3 or 4 pieces – Understands what twoť means – Copies a circle with a pencil or crayon – Turns book pages one at a time – Builds towers of more than 6 blocks – Screws and unscrews jar lids or turns the door handleMovement/Physical Development- Climbs well – Runs easily – Pedals a tricycle (3-wheel bike) – Walks up and downstairs, one foot on each stepDoing up buttons is a skill more usually seen in 5-year-olds.

Milestones of 12-month-old child are as follows:Social and Emotional- Is shy or nervous with strangers- Cries when mom or dad leaves- Has favourite things and people camera- Shows fear in some situations- Hands you a book when he wants to hear a story- Repeats sounds or actions to get attention- Puts out arm or leg to help with dressing – Plays games such as peek-a-booť and pat-a-cakeť Language/Communication- Responds to simple spoken requests- Uses simple gestures, like shaking head noť or waving bye-byeť- Makes sounds with changes in tone (sounds more like speech)- Says mamať and dadať and exclamations like uh-oh!ť- Tries to say words you sayCognitive (learning, thinking, problem-solving)- Explores things in different ways, like shaking, banging, throwing- Finds hidden things easily- Looks at the right picture or thing when it’s named- Copies gestures- Starts to use things correctly; for example, drinks from a cup, brushes hair- Bangs two things together- Puts things in a container, takes things out of a container- Lets things go without help- Pokes with index (pointer) finger – Follows simple directions like pick up the toyťMovement/Physical Development- Gets to a sitting position without help – Pulls up to stand, walks holding on to furniture (cruisingť)- May take a few steps without holding on- May stand alone

Based on the presentation, the developmental age of the child is 8 months.The primitive reflexes are indicators of functional integrity and maturity. The majority of reflexes do not persist beyond 6 months of age. There are 13 reflexes of importance, including:- Moro reflex- Startle reflex- Rooting reflex- Sucking reflex- Grasp reflex- Voluntary palmar grasp reflex- Voluntary reach reflex- Stepping reflex- Asymmetrical tonic neck reflex (ATNR)- Parachute reflex- Plantar reflex- Tendon reflex- ClonusIt is interesting to note that gastrocolic reflex is not a primitive reflex.Ninety-five per cent of reflexes will have disappeared by the ages shown below:- 6 weeks: Stepping- 3-4 months: Palmar grasp and Moro- 6 months: Sucking, rooting, and asymmetrical tonic neck reflex (ATNR)

Generally, bed-wetting before age 7 isn’t a concern as the child may still be developing night-time bladder control. The child is less than 5 years and most children will outgrow bed-wetting on their own. Therefore only reassurance and behavioural therapy are suggested at this stage.

Milestones of 6 monthsSocial and EmotionalKnows familiar faces and begins to know if someone is a stranger Likes to play with others, especially parents Responds to other people’s emotions and often seems happy Likes to look at self in a mirror Language/CommunicationResponds to sounds by making sounds Strings vowels together when babbling (ah,ť eh,ť ohť) and likes taking turns with the parent while making sounds Responds to own name Makes sounds to show joy and displeasure Begins to say consonant sounds (jabbering with m,ť bť) Cognitive (learning, thinking, problem-solving)Looks around at things nearby Brings things to mouth Shows curiosity about things and tries to get things that are out of reach Begins to pass things from one hand to the other Movement/Physical DevelopmentRolls over in both directions (front to back, back to front) Begins to sit without support When standing, supports weight on legs and might bounce Rocks back and forth, sometimes crawling backwards before moving forward

Primitive reflexes are central nervous system responses, many of which disappear as a child matures. Retention of these reflexes may point to atypical neurology such as in cerebral palsy or stroke. However, some persist into adulthood. The stepping reflex is present from birth and normally disappears by 6 weeks, while the moro reflex is present from birth to about 4 months. The asymmetrical tonic neck reflex disappears by about 6 months. Reflexes that persist include the head righting reflex which develops at 6 months, and the parachute reflex which develops at 9 months.

4-year-old milestonesSocial and EmotionalEnjoys doing new things Plays Momť and Dadť Is more and more creative with make-believe play Would rather play with other children than by himself Cooperates with other children Often can’t tell what’s real and what’s make-believe Talks about what she likes and what she is interested in Language/CommunicationKnows some basic rules of grammar, such as correctly using heť and sheť Sings a song or says a poem from memory such as the Itsy Bitsy Spiderť or the Wheels on the Busť Tells stories Can say first and last nameCognitive (learning, thinking, problem-solving)Names some colours and some numbers Understands the idea of counting Starts to understand time Remembers parts of a story Understands the idea of sameť and differentť Draws a person with 2 to 4 body parts Uses scissors Starts to copy some capital letters Plays board or card games Tells you what he thinks is going to happen next in a book Movement/Physical DevelopmentHops and stands on one foot up to 2 seconds Catches a bounced ball most of the time Pours, cuts with supervision, and mashes own food

A 2 year old child who is developing normally should be able to point to three body parts, identify familiar objects in his environment such as a crayon or a toy and follow simple instructions.At 3 years old he should be able to copy a circle, jump up and down and name three colours.

This child is experiencing delayed speech. By the age of 2, a child should be able to combine at least 2 words to make a very simple sentence.

At the age of 18 months, Gertrude should be able to follow a one step command. At this age she would also be capable of putting words together in 1 or 2 word phrases, scribbling, throwing a ball, and building a tower of four cubes. At 2 she should be able to feed herself with a spoon or a fork, copy a vertical line, ride a tricycle, kick a ball and balance on one foot. Activities such as jumping will follow later on in her development at 3 years.

At 7 months, children are expected to sit briefly leaning forward on their hands, reach and grasp objects, transfer objects from hand to hand, and babble. Children are usually expected to wave goodbye or grasp objects with their fingers or thumb at around 10 months and older.

At the age of three years a child is to be able to dress and undress himself with supervision, eat with a spoon and fork, build a tower with 9 cubes, give their full name and copy a circle. The child will not be able to make good cuts with scissions until he is about 5 years old.

A three-year child’s typical developmental milestones include walking up and down the stairs with alternating feet, jumping in a place with two feet together, and jumping forward for about 2 feet. The child can pedal a tricycle and can throw a ball over and underhand. An average child should start walking around 12-14 months of age and should be investigated as early as 18 months if they do not begin to walk. Skipping can be done by a child of 5 years of age. A child of 6-7 years of age can ride a bike with stabilizers and can balance on one foot for 20 seconds.

Among the given options a 2-year-old child with normal developmental milestones will be able to pull and push large wheeled toys and squat to play with toys on the floor.Other options:- Bouncing and catching a ball is learnt by the age of 5.- The ability to pedal a tricycle should be attained by 3 years of age, not 2.- A child can walk on tip-toe by 2.5 and run on tip-toe by (option D) 3 years of age, not 2.- The ability to momentarily maintain balance using one leg (option E) should be attained by 3 years.

By the age of 3 months Jasmine should startle to loud noises, recognise her parents voices and turn to them when they are speaking, and should quiet down or smile at the sound of a familiar voice when crying. She should also cry when she is uncomfortable or irritated. By the time Jasmine is 9 months old she would begin to understand and respond to the word ‘no’ as well as other easy commands. She would be able vocalise and babble with repetitive sounds, and imitate adults’ playful sounds. She would be much less likely startled by loud noises.
