I hate to rain on your parade, but research and my experience show that baby signs delay speech. All the children I've known whose parents have taught them signs (5 kids from 3 different families) have been very slow to talk. If the child has a way to communicate nonverbally, he or she will not feel driven to learn verbal communication. Sure, baby signs are cute and convenient for the parent because they're easy to teach and interpret, but think about later on when your child is way behind the other kids. Plus, other adults and children don't know baby signs, so think of your child's frustration in trying to communicate with anyone but his/her parents. Why not spend the time it would take teaching signs to your child, talking to him/her instead? Children who are talked to and read to a lot have bigger vocabularies and higher IQs. Besides, if they are old enough to do signs, they are old enough to learn to talk. My son had a 60 word vocab by 1 year old, and now speaks in sentences at 22 months. His friend learned baby signs, is just now starting to talk at the age of 2.
