My DS is 3yr 10 months and has some development delay. We are on day 4 of potty training and not doing too bad at all except he wont part with his wee. He's been pooing in the potty fine but more or less trying his bed to hold it in as much as he can then usually being that desperate he has an accident. Anyone familiar with this?. Ive also tried to get him to use the loo like his brothers but hes not having any of it. Any advice would be great.
