This is to get an idea how a signing baby develops language during his first month to about 8 - 10 months before developing a first sign word. I cannot subtitle a 12 minute long video clip. For non signers and new ones, you can scale to video clips to observe our deaf Noam at 4;5 and 7;0 starts using hands to develop “pre” sign vocabulary, known as protoword. Also you can watch how mom and her infant interact.

More current research information on babbling and the transition to prototypical sign can be found in chapter 9 “The Form of Early Signs: Explaining Signing Children’s Articulatory Development” by Richard Meier in an edited book: Schick, Marschark, & Spencer.
