My son is 28 months old and he will not talk he understands everything I say to him and makes noises for the relivent animals and objects i.e train, cows, cats etc I've spoken to a health visitor and she said there's nothing to worry about he's got communication skills there. Can anyone suggest any things I can do to help him I already have flash cards, I sing nursery rhymes he goes to playgroup and sees other children. Its so frustrating!!
