@rangerr I lost something….was your step brother sleeping in your bed when he peed? That has me a little confused! I mean, you tied it in with him coloring on the walls so it was like….did he do it on purpose?
As for a parent’s tale, when my oldest was well potty trained, and had been sleeping dry through the night for a couple of months…suddenly she started wetting the bed. It upset her more than anyone! Not a problem. I put a towel down on the bed (Which she loved…she slept with us in our king bed, and when she got excited about her own little place, I felt kind of bad, having not realized that when we put her to bed she might have felt adrift on this huge island of a bed….) AND I got a 30 pack box of Pull Ups (which I don’t believe in for actual, initial potty-training purposes), which, she and I agreed, would be nice. Just put one Pull Up a night, for the next 30 nights, and, viola! At the end of the month the problem was resolved. Simply because she wasn’t stressing about it any more.
But… @rangerr‘s story seems a bit different than that, what with her being only 16, 17 (?) and dealing with a younger step brother.
