Hi everyone, I lurk here quote a lot and you've all been very helpful before. Our 19 month old little boy is reluctant to speak, he will say mama and dadda. But nothing else. The fiancee is worried he is autistic, i am not. He literally understands everything we tell him, he knows his colours, animals, the noises they make, nursery rhymes he dances along too. If we tell him its tea time/ bed time/ bath time etc, he knows exactly what we are saying. He literally grunts at us, holds our hand and takes us where he wants to go. he babbles to himself, which is really cute, then he'll just stop and start grunting again. I get frustrated because i know he knows what we are saying, is he just being lazy or should we be worried? Thanks in advance.
