My son is now 29 months, he has been potty trained since about 25 months old. He’s doing great, the odd little accident but nothing much! Except when he is with hubbys cousin (who is DS’s) godmother. He gets on great with her and loves spending time with her 
but I’ve noticed that every time he’s with her he has accidents, he won’t tell her when he needs the loo. A few weeks ago she was minding him at our house, when I arrived back he’d had four accidents. We haven’t had an accident at home since we started potty training! 
has anyone any advice? He’s fine when left with grandparents, my friend etc. I’m wondering does he maybe see her as more of a friend than an adult if that makes sense? I’ve tried talking to him and asking why he doesn’t tell her but nothing!! Any tips welcome!!
