There is no Potty like Home

Nolan is doing really well with the potty training at home. At home he mostly goes by himself. Sometimes he needs a reminder. When I remind him he goes without a fuss. No major accidents.

Perfect right? Wrong! He will not go on any other potty, but those at home. He won't even use Mamaw's potty. He goes outside when he is at her house. This week he had two major accidents. He waits until he can't stand it. He gets very grumpy and impossible. I try to get him to go, but he refuses to. Out and out throwing a fit refusing. Nothing seems to work. Then he goes in his pants. Last Sunday at church, I took him outside to go. Going outside is not a problem. He will pee anywhere if we are outside.

A friend of mine used to carry her sons potty seat with her everywhere. He used one of those that sits on the big toilet. She would wrap it up in a plastic bag and stick it in a big duffel bag and take it everywhere. I used to think she was nuts. I may have even thought those forbidden words, "I will never do that for my child." What I wouldn't give right now to be able to carry Nolan's potty seat with me. I would do it in a heartbeat! Unfortunately, Nolan refuses to sit on a potty seat. He goes on the big potty, at home. I can't carry our toilet with me!

Deep down I know this is a phase he will outgrow. He will learn to go to the bathroom when he isn't home. Right now though it is infuriating. Have any of you had this problem? Any ideas how to solve it? Besides never leaving the house or letting him pee outside everywhere?
