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.
