Babies develop at their own pace, so it's impossible to tell exactly when your child will learn a given skill. The developmental steps listed below will give you a general idea of the changes you can expect, but don't be alarmed if your own baby's development takes a slightly different course.
Newborn through 2 months
The infant can lift and turn the head when lying on its back.
The neck is unable to support the head when pulled to a sitting position.
The hands are fisted, the arms are flexed.
Primitive reflexes are in full operation. These include:
rooting and sucking -- turns head in search of nipple when cheek is touched and begins to suck when nipple touches lips.
tonic neck response -- left leg extends when infant gazes to the left, while right arm and leg flex inward, and vice versa.
palmar hand grasp -- infant closes its hand and "grips" your finger.
plantar grasp -- infant flexes the toes and forefoot.
Babinski reflex -- toes fan outward when sole of foot is stroked.
Moro reflex -- extends arms then bends and pulls them in toward body.
placing -- leg extends when sole of foot is stimulated.
stepping and walking -- takes brisk steps when both feet placed on a surface, with body supported.
