I have taught kindergarten children (in formal schooling so aged 5) who don't know ANY colours and cannot count at all so i wouldn't be concerned at all about that. My DS couldn't count at just turned 3 and I couldn't care less, I think there is too much pressure on kids these days to do things way before they need to.

Speech therapy can be very useful and can make a big difference especially if you get in early like you are doing.

Huge hugs, I think you are a great mum- heck you do more with her than I do with my kids LOL
