Development Checklist request | Autism PDD

If you take your newborn to the nearest junior high and look at the 12-year-olds surging through the doors, you'll find it hard to beleive that this is where your tiny infant will be in only a dozen years. And 12 years from now, you'll wonder how it all went so quickly.

Wherever your children are on the road from birth to adolescence, this birth to age 12 timeline will show you some of the milestones you can look forward to, or remember fondly. Keep in mind that, as with any discussion of development, the ages listed here are only averages. Your child will develop according to her unique pattern. Within the wide range that is normal, individual variations don't mean much - the child who walks at nine months isn't anymore more likely to be a great athlete than the child who walks at 18 months. And because the ranges are so wide, many of these milestones will overlap. Your baby may crawl before she sits up alone, for example, while another baby will sit before he crawls. That's normal, too.

Nobody is more excited about a child's achievements than the parents. When your son or daughter learns to stand alone, or pedal a tricycle, or kick a ball into the soccer goal - go ahead, celebrate! Cherish these steps along the road to growing up - each one is speciall.
