Sorry if this is posted in the wrong place.
DS is 16 months and mixes words and signs. I did a baby sign class with him, and I think nursery do baby signing.
He's started tapping his index finger onto his other palm and gets frustrated when I don't understand what he's trying to say.
He also sometimes circles his palm with the index finger of the other hand, I have no idea what this could be either!
Hoping someone might know what these could be.
