Good Morning Laura,
My son is now 19 months old, so he's becoming more vocal, but I want him to learn ASL anyways. Does he need to do exact signs or should I just help him perfect them later since gross motor skills delvelop later on? For example, for the sign, "more", he points only his index fingers together vs pointing all of his fingers in a bunch together, and I taught him the sign for, "eat" this morning and he just puts both of his fists to his cheeks vs pointing all the fingers on one hand into one cheek.
Also, is there a huge difference between ASL and Baby Sign Language?
