DS is 13 months and does a lot of babbling but still no actual words. He has a reasonable range of sounds and we get Dada quite a lot, but it doesn't have a meaning, it's just a noise.
I read with him and I try to emphasise the words of the things he is around: ball, cat etc.
When should I realistically expect him to start using a few words and is there anything else I can do to help develop this?
