Waiting till summer to start potty training

If you can, it's best till watil till the summer or at least until it's a bit warmer to start training your child to use a potty.
That way, it won't matter so much if (s)he accidently has a wee because (s)he won't get cold, and it'll also be quicker to change his clothes than in winter, when he's got several layers of clothes on.
