DS is 3yrs 3months and has been out of nappies for about 6 months. He's been a bit up and down but has had periods where he's been really good and I know he has the ability to stay clean and dry. He's currently the worst he's been and is wetting and soiling regularly even though we take him to the toilet frequently. He has completely stopped asking to go to the toilet or telling us he needs a wee/poo. If we ask him why he went in his pants he says 'I don't know' or 'because I said so'. He just doesn't seem to care at all. Incentives work briefly then he gets bored. Today I told him pants aren't to do wees and poos in and if he carries on then he'll have to wear a nappy. From what I've read this isn't advised but I'm feeling desperate and don't know what else to do. Has anyone this?
