Thanks so much for all of your speedy replies.

Tanstar, I hope your DS grows out of quickly too. I've tried a dvd too but hasn't worked so far, and I thought Peppa Pig could fix anything!

CheezelMonster I'm so glad Mr Moo grew out of it, it gives me hope that DS will do the same eventually.

Det, that is a possibility. He is in undies during the day but I still put a nappy on him for sleeps just in case. It's definitely worth looking into, I'll see what happens when I mention it next time, probably tomorrow!

nothing2lose that's a really good thought, I'm pretty sure he's not hot but I'll keep an eye on him to make sure.

Thanks again, good to know I'm not alone!
