Our adopted son has lived with us for just under four months - he's almost 5 and is rarely ever dry during the day.
He's in normal pants (other than training pants for school), completely dry overnight and even wakes up in the night to go to the toilet if he needs a wee. But during the day, he rarely ever takes himself to the toilet and feels like me and my partner are having to constantly remind him to go. If we don't, he'll wet himself and won't tell us that he's done so until we discover the accident in his pants when we get him to try for a wee.
At first we assumed he was voiding as would usually happen when he was engrossed in play/screens but even getting him to go to the toilet before those won't always work. If we ask him if he needs a wee he says 'no' so I've changed tact and tell him simply it's toilet time - he throws tantrums about going and then when he gets to the toilet, he regularly pulls his pants down and stands poised by the toilet but adamantly tells us nothing is going to come out (he does stand up wee's so if nothing comes out we get him to sit), to then 15-20 minutes later find he's had an accident anyway.
When he has an accident we point it out and ask him when he had it and he always acknowledges when it was (ie when I was playing/watching TV) and ask him what he should have done - and he'll usually reply with I should have told you I needed one/stopped what I was doing to go. Then we get him a clean pair of pants/trousers for him to put on and move on. We never get cross at him, shame him or compare him to anyone - I feel we're really patient. He regularly apologises after we discover the accident which we say he doesn't need to do, and we tell him accidents do happen and gently remind him to go to the toilet when he needs to go next time and leave it at that.
We've talked to him about how he can pause whatever he's doing and how only he knows when he needs the toilet so when he gets that feeling in his tummy, he needs to take himself to the toilet. But nothing seems to sink in. We've tried rewarding him with chocolate, setting wee alarms, praising him when he goes and celebrating the dry days, but struggling to get anything to stick. In the early days we put him back to pull ups as he was soiling himself too, but we don't want to go backwards again as that didn't really seem to work either and he finds normal pants comfortable.
I know he's been through a big change moving to his new family, he's just started school properly too recently and wears training pants during the day, but most days they're wet too - which we completely expected.
Being on his case and having to remind him/deal with the tantrums is getting tiring and I'm worried it's rubbing off on him and making him feel anxious about toileting - he clearly resents being told to go. Also concerned that appearing so unbothered by his accidents might be giving him the impression that he can just relieve himself in his pants. Are we doing anything wrong?
