This is a great example of sign babbling! G is a soda (hearing sibling of a deaf adult (kid here), and E is his deaf big brother. G knows he needs to use #asl to communicate with his bro, E. Towards the end, the sign babbling becomes clear signs & thus begins a “lively discussion” among the brothers. G already has over 100 plus identified actual signs and will clearly become multilingual. That’s what siblinghood should always look like. The family has been learning to sign for the last few years
