BabyCenter.com
A great website for those who are pregnant or who have little ones is www.babycenter.com. You enter your due date or child's age and subscribe for free. You get an email each week showing how your baby is growing, and if your child is born, the email tells you things your baby should be doing and suggestions for encouraging his/her development. There is a section with parents' questions and answers which is helpful. It is a really great resource.
