DS is 2.9 and the last few days he has started the strange thing of wanting to be completely naked when he goes to the loo. He usually takes his pants and trousers (sometimes socks) off anyway in case of any dribbles but now he totally freaks out and won't go near the toilet unless he takes off every bit of clothing. I keep telling him he only needs to take his pants off but he insists on stripping off. Our bathroom isn't the warmest room, especially in a morning, so he will sit there shivering with goose bumps complaining that he's 'feezing' whilst he does his business. What is it all about??
