I have this same struggle with my almost six-year old, newly ADHD+anxiety diagnosed son. Some days he does great, and then he’ll go through a streak where he has pee accidents once or twice a day. He throws a fit if we remind him to potty, or if we can see that he has to go but isn’t going (he tends to get wild and act out if he has to pee badly). It’s exhausting. I’ve even had to buy him more pants because most of his nicer ones are elsewhere (school or after care) in the laundry! Looking forward to seeing what others suggest.
