My Ds 30 months won't talk. Has dd(5) to relay on doing all the talking. DS will say few words and mutter in his own language but would rather hold hand and take you to anything he wants. Have sent him to nursery 2 AM's a week to try to improve his speech. Been to see HV and has said will refer him for SP therepy also said not worried as he interacts well without using lang.It's very fustratating as Dd was very quick at talking. Am i right to be concerned or am i just being paranoid.
