It's a great question and I'm sure there are many parents who occasionally look at their kids' behavior and think, "Is this normal?!" That's why it's so important to take any and all concerns about your children's physical, emotional and social development to your pediatrician. He or she has seen thousands of kids the same age as yours and therefore has a much better handle on what's "normal" and what isn't. Don't wait. Don't worry on your own. Talk to your pediatrician.

I would also suggest, that you check out the work of Susan N. Schriber Orloff, CEO and executive director of Children’s Special Services, LLC, an Atlanta-based occupational therapy service for children with developmental and learning delays. Her book, Learning Re-enabled, is a practical guide for parents, teachers and therapists.

She recently wrote a guest blog for me entitled "Quirky Kids: When to worry and when not to" http://blog.anniefox.com/2011/03/12/guest-blogger-quirky-kids-when-to-worry/
