He is three - doesn't really talk in full sentences yet (though he is getting there). But he knows his numbers, colours, letters etc.
We had this conversation earlier:
Ds (lines up three cars): How many cars I got?
Me: Lets see ... one, two ... (looks at ds to supply the next number)
Ds (rolls eyes): I not do it for you mummy!
Oh, and every night before he goes to sleep, he says "Don't getfer your trousers wet mummy!" Wtf???
