Well, I don’t carry potty chairs but I have had this problem too. I was surprised that my oldest daughter went in her car seat one time after being potty trained.??? When she had problems with other toilets I would put a diaper on her when we left the house to go somewhere. She didn’t like this and asked why she had to wear a diaper like a baby. I told her that we were going to be out of the house and she doesn’t like to go to the toilet and I don’t have time to clean her messes up when she doesn’t act like a “Big Girl”. After a couple of times of wearing that diaper she decided that it was enough. I told her what I expected of her. I always kept the couple of extra diapers near the seat just in case she was having problems and needed reminding. Eventually after a few times she said, “Mommy, I think I can go in the big potty when we are out.” I was so relieved. So, when my other kids were learning I knew what to do without having to worry about an accident.
Sometimes children don’t like to go on the big potty for reasons. Some of the reasons my children came up with was…. They didn’t like the noise the big potty made. They also were afraid the swirling water would take them too. Then their was that they would fall in and get their clothes wet/poopy. So, I learned to that they have reasons why they won’t go in that big scarry potty.
It was a little different with short boys though…… especially when the lid hits them in the pee pee the second time they try it. 🙁 Also if you put a few cheerios in the toilet for boys to hit the target it gives them something to aim for instead of the lid. 🙂
The good news is they will learn eventually. I don’t know of any kids that wear diapers…..Only a few adults but they have been potty trained and because of age have regressed….. Tehe he
