Isn’t saying any words 😩

16 month isn’t saying any words, he try’s but it’s not coming out. I’m so worried. He is in speech therapy and I don’t feel it’s any help at all. She just plays with him and thats what I do.

Other than trying to talk some words, he knows all of his body parts by pointing at them and knows where everything is in the house. Just feel he doesn’t wanna talk. We try and try and try. Should I be really worried?
