Language Acquisition in Signing and Non-Signing Children

I found this chart on the Baby Sign Shine blog. It compares the language acquisition of signing and non-signing babies and toddlers. My daughter signed her first word at 7.5 months. She was saying her first word by 9 months. She signed her first two-word sentence at 13 months and used at least 250 signs by 18 months. At 2.5 she knows all her letters, and some of their sounds.

I definitely agree that sign language helps a child's vocabulary. I've been watching videos online ( to help me get started. I would love it if you had some online video resources you could redirect me to.
