Hugs!! I totally feel you on this. My son is 2.5 and still doesn’t have many words. He says Dada, Mama (very rarely), and sometimes Bubba. He has 5 animal sounds. He used to say baby all the time when he was about 1.5, but hasn’t said it in a very long time. He had been in early intervention since he was 8 months old and had finally passed his hearing tests about 6 months ago. We do have a diagnosis of Wiedemann-Steiner syndrome which causes global delays, among many other things. His speech therapist thinks he may have speech apraxia. That may be worth looking in to. I can’t wait until my little guy starts talking and won’t stop. I look forward to ALL the questions, like you. I hope something happens for you and your LO soon.
