Baby or infant sign langauge is the use of American Sign Language (ASL) to communicate with infants and toddlers. Sign language is a perfect transition to verbal speech because hand-eye coordination develops earlier than verbal abilities. By giving your child the ability to communicate earlier you'll likely experience less frustration and suffer fewer tantrums.  Every infant should be taught at least a few of the most common signs such as eat, change (diaper), help me, please, milk, and bedtime.  By sticking with ASL many nannies, babysitters and other parents may already be familiar with your baby's signing.
