My son is 19mos now.. i am bit concerned about his speech although he babbles a lot and "talk" a lot but he always just say the word "ah eh" eventho it feels like we are having conversation his "ah eh" feels like he is saying so much into it. But he know few words such as mama, dada, dede, baba, aba, papa and the other day i ask him to say car and he said "kahh" .. is this normal? Eventho he know some words, "ah eh" is everything? Also, i noticed that he hand flaps when he gets excited.. we seen a pedia at his 18mos appointment and she is not worried as she seen herself that my son know what he is doing and understand things or instructions, although he doesnt point but he does it with full hands..
I need some advise please.. i am having anxiety and it stress me out..
