See if can help.
whenever the daughter need something
she will tap on someone shoulder and point towards what she wants.
Adult : you want this sweet.
Girl : Nod her head.
Adult : Give her the sweet.
Girl : Case closed without opening her month.
Suggest, ask her and point to what she dun want, i.e give her toys when she point to sweet. slowwly she will try to make some noise to push her point.
My cousin son have this case too. Cause he got more them enough people to give him the attention.
But he has break the sound, now...very noisy...
