Physical Development

Not all babies are physically precocious. Your 11-month-old may be perfectly happy sitting or crawling, and not yet interested in pulling herself up. Chances are, she's just proceeding at her own measured pace. Babies who acquire motor skills more slowly are generally sure of their movements and less likely to hurt themselves by, say, falling backwards when they finally stand. They simply prefer to master an entire process--such as pulling up, balancing, and gently sitting down again--before adding it to their repertoire. However, if you think your child's hesitancy goes beyond normal levels, it's best to have your pediatrician take a look, if only to reassure you.

Social Development

Your little mimic may be imitating your every move. She'll rub her mouth while you brush your teeth, comb her hair with her fingers as you do yours, and hang on the refrigerator door when you try to get something to eat. This desire to imitate you is a reflection of her attachment to the most incredible, wonderful person in her world. Although all this adoration may be wearing at times, try to enjoy it: No one, including your child, will ever find you this perfect again.

Intellectual Development

As discipline becomes more of an issue, it's important to remember that your little one's explorations are essential to her development. Studies have found that the best way to get your baby to listen is to discipline her only when absolutely necessary--when she is in danger, or when her behavior is negatively affecting others. Whenever possible, she should have room to (safely) roam as she learns about her world.

Note: The information above offers general guidelines, but all babies develop differently, and few hit their milestones precisely when the conventional wisdom says they should. If your child was born prematurely, you may want to use your due date as a baseline for following baby's development.
