DS is 3. We have been trying to potty train for the best part of a year. Yesterday I decided I had had enough and he was going in pants and only going near a pull up at bedtime. So far today he's done nothing in the toilet despite me asking him constantly if he needs to go and putting him on it every half an hour yet he has pooed himself and not told me and I have found him sat in a puddle of piss not really caring 3 times. He needs to be trained, I've tried everything yet nothing is sinking into his head and I'm ashamed to say I've shouted quite a bit.
Any suggestions would be great as I'm pretty sure I'm going insane!!
