Lora Heller is the author of Sign Language for Kids, geared toward school age kids, and Baby Fingers: Teaching Your Baby to Sign, a board book series for babies and toddlers. Both are published by Sterling. A music therapist, a teacher of the deaf and a New York City mother, Heller created Baby Fingers sign language and music programs in 2000 after her first child began to sign. Both of her children were communicating via sign language at 6½ months of age, and speaking in full sentences before the age of 2. Learn more about Baby Fingers at www.mybabyfingers.com.
