My DS2 didn't start talking until he was 2. The only explaination I was given was that it might have had something to do with him being born with a tongue tie, which was snipped at 5 weeks, and because his teeth were slow in coming through.

DS2 used to hum instead of talking. Drs and ECHNs disagreed with me and told me he wasn't humming. I don't know what they thought he was doing though?! I was constantly told to give it time and he will come good. I was told not to bother with a speech therapist as they felt he didn't need one as he had/has fantastic comprehension and they felt he just was shy and would talk in his own time. It was also suggested that his much older siblings were talking for him and that may be why he wasn't a talker as yet.

He talks heaps now and will be 4 in Feb. I am still concerned about his speech and will be seeking out a speech therapist this coming year. He has loads & loads of words and puts together full sentences, but I feel like his speech is still about 12 months behind his peers.
