You'd be surprised. It all depends on if the parents are potty training like they should, or if they're even doing it. Some parents expect day care / babysitters to do it for them. My boyfriend's mom keeps kids and she's got a 4 1/2 year old who isn't potty trained at all... he wears pullups all day and cries when he pees in it. His moms said she "doesn't have time to train him"... How you can have a kid and not potty train them is beyond me.

My little cousin wasn't fully potty trained at 3 because she had terrible eczema and couldn't get a good effective treatment until she was about 2 and a half. It was too painful for her to be potty trained before then.

I wasn't potty trained until I was about 3 because I couldn't walk until I was 2.5 - but once I was walking, I was out of those damn diapers. But anyway - most 3 year olds that I work with are day time toilet trained, but don't get out of night time nappies for at least another 6 months. For some kids it takes longer to control their bladder at night. My sister was almost 7 when she stopped wetting the bed every night. My other sister took 6 months after she started daytime training and my brother was like me - as soon as he was out of nappies in the daytime he was out of them at night time.

My daughter is nearly 3 and I'm pulling my hair out trying to potty train her. its got nothing to do with me not doing anything or trying hard enough, this past year I have tried everything to no avail. She simply will not use a potty, toilet or child toilet seat. She will actually make herself ill, holding everything in until she's near a nappy or, strangely, a towel. There's nothing psychologically or physically wrong with her. Trouble with potty training isn't always down to a lazy parent.
