Sign With Your Baby: How to Communicate With Infants Before They Can Speak
was truly one of the ground-breaking
references on infant signing. The concept started getting
traction in the late 1990s and signing to your infant became
quite mainstream by the mid-2000s. Garica's
SIGN with your BABY - Quick Start Baby Sign Language (ASL) Kit: Includes Book, How-to DVD, Quick Reference Guide
was another great
publication released in 2005.
