DS is 2.5 and we have been making some attempts at potty training recently. He didn't seem to be very ready and started getting upset so we stopped for a bit.
Recently though he's started getting very distressed about his own functions - yesterday at nursery he cried and cried because he weed all over his clothes when his key worker was changing him, even though she didn't make any kind of fuss about it at all.
Today he was in bed for his nap and did a poo, so he removed his own nappy and came downstairs with a very poo-ey bum
I didn't react at all crossly or shocked, just said very matter of factly 'shall we get your bottom all cleaned up and put a new nappy on' and he said yes, but then he wouldn't let me wipe his bottom, I had to chase him round the bathroom to do it. He was getting really upset and I said 'poo is nothing to worry about, everyone poos, Mummy poos, Daddy poos' etc etc and he said 'noooo, poo is nasty and horrible'
He's said this kind of thing before, and I honestly don't know where he has got it from, we've never said that or implied it in front of him or anything.
How do I help him get over this? I feel sure this is part of why he doesn't want to potty train, but I don't know how to help. Anyone been through similar?
TIA
