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.
According to a new NHTSA survey, the following are the five most significant and commonly observed mistakes made by parents and caregivers when using and installing car seats and booster seats:
Wrong harness slot used -- The harness straps used to hold the child in the car seat were positioned either too low or too high;
Harness chest clip positioned over the abdomen rather than the chest or not used at all;
Loose car seat installation -- The restraint system moved more than two inches side-to-side or front to back; anything more than one inch is too much.
Loose harness -- More than two inches of total slack between the child and the harness strap; there should be no slack.
Seat belt placement was wrong -- Lap belt resting over the stomach and/or shoulder belt on the child's neck or face.
