The document outlines the developmental milestones of hand reflexes and motor skills in infants, detailing key ages for various grasp techniques and other physical abilities. It introduces mnemonics to help remember the ages associated with specific skills such as grasping, building towers, and using utensils. Additionally, it tracks the evolution of head control and mobility milestones from birth to two years.

1. - DR.AKIF A.B

2. -Involutary grasp reflex diappears at 2-3months
- Voluntary grasp reflex develop at 4th month

3. -Hand regard is seen in babies between 3-5 months of age
- It occurs when a baby is seen lying supine, watching the movement of the hands.
- persistence beyond 5months = Abnormal
Mnemonic: In hand there are 5 fingers
and persistence beyond 5months is
abnormal

4. -Bidextrous approach ; approaching towards object by both hands = 4-5months
- unidextrous approach: approaching towards object by both hands= 5-6months
-Ulnar grasp : holding things with ulnar(medial) side of palm = 6-7months
- radial grasp : holding things with radial(lateral) side of palm = 7-9months
-Immature pincer grasp: partially holding pen between index and thumb = 9-10months
- mature pincer grasp: fully holding pen between index and thumb = 11-12 months

APPROACH
Mnemonic: 1) ulnar means medial ,which has 6letters;; so 6months
2) radial means lateral, which has 7 letters= so 7months
3) unidextrous – uni- 3letters-multiply by 2= 6 = so 6months
4) Bidextrous – Bi- 2letters -multiply by 2= 4 = so 4 months

7. Making tower of 2cubes: 13- 15months
Making tower of 10cubes: 36months
Making tower of 6cubes: 24months
Mnemonic: 13 months = 13 = minus between 1 &3 = 2
so 3-1=2=2cubes
Mnemonic: 36 months = 3&6 = add 3 &6= 9
so 36 months = 9cubes (approx 10)
Mnemonic: 24months =2 &4= add 2 &4= 6
so 24months =6cubes

10. -Uses cup and spoon but spills over all = 12months
- Cup without spilling = 15months
-Spoon without spilling = 18months

11. -Turns 2-3 pages simultaneously : 18months
- Turns each page separately : 2years

12. -Involutary grasp reflex diappears at 2-3months
- Voluntary grasp reflex develop at 4th month
-Hand regard is seen in babies between 3-5 months of age
-Bidextrous approach ; approaching towards object by both hands = 4-5months
- unidextrous approach: approaching towards object by both hands= 5-6months
-1month: Lifts head spontaneously in prone position
- 1.5months: lifts head spontaneously in supine position
- 3 months: lifts head in prone position on both arms/
partial head control in supine
- 6months: lifts head in prone position on both extended hands/
complete head control/ sitting with support

14. -Ulnar grasp : holding things with ulnar(medial) side of palm = 6-7months
- radial grasp : holding things with radial(lateral) side of palm = 7-9months
-Immature pincer grasp: partially holding pen between index and thumb = 9-10months
- mature pincer grasp: fully holding pen between index and thumb = 11-12 months
-Voluntary release of objects/ transfer between hands : 7months
-Releases objects on request : 12 months
-Uses cup and spoon but spills over all = 12months
-7 months:: lifts head in prone position on one extended hand
-8 months : sitting without support/crawling
-9months Pivots/ standing with support
- 10 months: Creeping/walking with support
-12 months : standing without support

16. Making tower of 2cubes: 13- 15months
Making tower of 6cubes: 24months
Making tower of 10cubes: 36months
-Turns 2-3 pages simultaneously : 18months
- Turns each page separately : 2years
- Cup without spilling = 15months
-Spoon without spilling = 18month
-Copies line =2yrs…..circle=3yrs
- scribbles : 15months
-13-15months: walking without support
-15 months: Creeps on stairs
-18months: Runs
-2yrs: Walking backwards/ walking on stairs one by one step

22. LIFTS HEAD SPONTANEOUSLY – 6WEEKS(1.5months)
PARTIAL HEAD(NECK) CONTROL – 3months
COMPLETE HEAD CONTROL - 6 months
Mnemonic : multiply by 2 each time: 1.5*2=3……3*2=6
Checked by pulling both hands to sit

26. (Mnemonic: first sits than stands and walks
with support first…..in sequence: 9,10-11,12,13-15)
