He had his adenoids taken out and tonsil age 3.5 for nasal congestion and snoring. This resolved the snoring, but he still speaks as if he is underwater, it's been a year and half. He is prone to colds which doesn't help. I had spoken to his teacher and she said the school won't worry about speech until age 7. Is this correct, should I try to refer him myself ? It can be hard to understand him, I often repeat the word correctly and he now noticed and says "I said that!" And gets a bit cross.
