My son is 22month old. He doesn't say any words. Just mutterings. But can make pitch sounds for words (if you understand what I mean) I didn't know I was having him. Till I was 37weeks (estimated) pregnant. I was on medication I shouldn't have been on when pregnant an had Mri an CT scan in what would have been late pregnancy. So don't know if he was Prem or what. But I'm worried about his speech. Even though he understands us completely. He just won't talk. Any advice would be greatful.
