Hello, Chrissa, and the rest of you who have had the same problem we do with our 6-year-old son. Chrissa, you could be writing about our son. We, too, have tried every combination of punishment and reward to no avail. He did not potty train until he was four - and then, we had to take away toys to get him potty trained at all. We had been trying to train him for a year and a half before he finally started to use the bathroom with any regularity.
Since then, he does not have accidents at night, and he only has pee accidents - a little leaks out, never the full amount, but enough to show up on his pants and require a change of clothes. And again, like so many of you, it seems that he gets too involved in playing and that is when he has the accident. He also does not seem to care at all if his pants are wet, although he does show some concern when he thinks about what the other kids would say, especially his neighbor friend who is older.
In the last week, however, he has started to have accidents in daycare (he spends his days there while school is out, it is not a new school to him, but for some reason he only started allowing his accidents this past week). I do not know what has led to this change. Both times, my husband has had to get him out of school immediately.
For a while the threat of buying him diapers was enough to make him "be good" for a few days at a time, but that seems to have faded. So this week, we will try this: If he wets himself at school, he will come home and stay home, and will not be allowed to play outside all day. On the days when we are both working, he will have to wear a diaper (that should be a fun morning). I will let you all know how that works.
I have read that some of these kids are ADHD. I don't think our son is, but I wonder if anyone else's kids have something in common with him - he is very smart (top in his class in reading and math) and very stubborn. He is also crafty and diabolical - for example, time outs never worked with him, since he could see that there was nothing holding him in the chair or the corner, so he would just leave. Taking away toys does not work anymore either, he will simply "make do" with his imagination, and acts as though the missing toy means nothing. And if we spank him, he hits us right back, hard. He also is subject to fits of rage when he does not get his way - fits that involve physical abuse on us, and no amount of reasoning, threatening or cajoling will bring him out of it - the best solution is to walk away, then the storm will eventually pass on its own.
It would really help if I could talk to someone who is going through or has gone through the same thing. Let me know if you are out there.
