Dd is not quite three and she mixes up her colours sometimes and she loves counting from 6 up to 10 but nor from one. She has conversations with dh and I but gets shy around people now.

It's good the cc staff are keeping an eye on her but seek professional advice before you worry to much.

We have books we read, we name the colours, ask what sounds the animals make, (horses go moo). We sing songs with counting eg 5 little ducks, little piggies.
