My ds is 22 months old, and is very forward (I know, I would say that) but he counts to 10, recognises numbers, shapes, colours, speaks in sentences, using the right tense in all conversations, etc etc (yawn) and now tells me when he's done a poo, but he won't let me near him for at least ten minutes after he's finished. Also, his poo is still very runny, only occasionally is it solid. Is that normal? Not like diarrheoa, just thick paste (god, can't believe I'm writing this). Is it too early to start with the potty, and is it possible when he poos like that?
