DS is almost 21mo.
He's not talking yet; words here and there and repeats stuff, but not conversations IYSWIM.
But, he wants to take his nappy off all the time - and this seems to be after he's pee'd/poo-ed in it. (bodysuits on to foil this!)
He's also asking for a "shoowr" a lot - he seems to have made a connection between peeing and the shower after he accidentally peed in the shower and got upset (and we reassured him).
So, try to train him or not?
