| Just after birth, a newborn can suck; that's
called the rooting reflex. |
| By 2 months, an infant can move the arms and
legs smoothly, hold the head at a 45-degree angle for a few minutes, and hold
an object for a brief time. |
| By 3 months, a child can sit supported,
although the head still bobs. |
| By 4 months, an infant can sit for 10 minutes
or so and maintain good control over the head. |
| By 5 months, an infant can put the feet in
the mouth and suck on the toes. |
| By 6 months, an infant can roll from the
stomach to the back. |
| By 7 months, an infant can sit easily with a
little support or alone. He or she can also bang two objects together.
|
| By 8 months, an infant can crawl and maybe
even stand with support. He or she can also attempt to pick up objects.
|
| By 9 months, an infant can master picking up
objects with the thumb and pointer finger and can crawl while grasping one
toy. |
| By 10 months, an infant can walk if both the
hands are held, or can even walk alone while holding on to the furniture.
Walking alone can begin anytime between 10 and 14 months. |
| By 11 months, an infant can wave, climb,
squat, stoop, and stand alone and may be able to grasp a spoon and bring it to
the mouth. |
| By 12 months, an infant can walk but still
prefers crawling to get around. He or she can point with the index finger and
take the covers off containers. |
| Infants usually begin to babble around the
seventh month and may begin forming short words by the first birthday. |
