Won't Potty Train at Aunt's House

I think it is as simple as wanting the control of this. It is almost like a power struggle. Kids do potty train completely when they are ready to do so and even though he is 3 and doing well at home, he just doesn't have it yet or he would be telling you even if it isn't in time to rush him to the potty. My suggestion to your sister is take the power struggle out of it. Ask him if he has to go potty, if he says no, let it go. When he is to the point of telling you all the time at home and doesn't have those accidents 50% of the time, he will also tell her he has to go.

The only reason I can think of that he doesn't like his aunts bathroom but will go in public bathrooms is he had something in there scare him, a spider, a painting, something we wouldn't look at as scary but he does and hasn't forgotten.

Maybe there is something about her bathroom that he doesn't like. It could be the silliest if things. my nieces and nephews always prefer to use our downstairs restroom even if it means they have to bypass the closest one and run downstairs. I have never asked them Y. My sisters youngest is almost 5 and he wont poop in the upstairs toilet at her house, he will urinate in it but always wants her to take him downstairs to the other one when he has to poop. You can talk to your son without making it sound lie his fault. try saying something you like about your sisters house or even the bathroom. like the colors. get him to discuss it. then ask if there is anything that he doesn't like about her house. you may find that there is something at her house that he either doesn't like or likes so much that it distracts him from remembering to go to the potty. once you get an idea of how he feels, if you are up for rewards (some parents don't like the reward system for potty training some do)then find a special reward that only happens at her house. Good luck and you maybe surprised at what your son will tell you once you get him talking ;)

do you ever go in there with him...is there something you do at home (maybe even something rewarding)that she may not do or know about...

be consistant with the either pull or diaper, once my DS was out of diapers he never put one back on...

he went from diaper to underwear during the day and pull up at night.

I'm so sorry if I don't know what I'm talking about,being as my daughter isn't potty trained yet...but maybe you should just let him be on strike at your sister's and he'll eventually grow out of it. You don't know why he's only refusing at your sister's, right? So, maybe he's got a good reason and he'll just get himself out of it if left alone...
I know the more I push my daughter about something the more she pushes back, so, if I stop pushing, she'll usually come around. Hope that helps.

Hi E.,

When at your sister's house, I would try to mimic the experience at your own home as much as possible: same potty chair or seat ring, same reward system, and so on.

There could very well be something at your sister's house that freaks him out--something benign, but still bothersome to him. Also, maybe your sister is assisting more or less than you are at home, and that bothers him.

I have a couple of friends who absolutely will not go #2 anywhere but home, and will reluctantly go #1, but like at work they will go to a bathroom no one uses, etc. So, it's not so strange that a 3 year old would have similar issues, you just have to overcome them.
