When I had my son 9 years ago, I was friendly with a girl at work who had a boy 6 months earlier.
She was one of these "modern" moms who was fervent about things like breastfeeding and using cloth diapers. She had huge issues with disposable diapers, saying that a baby in them couldn't feel any mess and that's why 3 years old is considered the norm for potty training nowadays.
While there may be some validity in her arguments, she took it pretty far and had her baby sitting on a potty seat every morning from the time he could sit up by himself (around 8 months or so).
When she had her second baby, the older boy was 2 years old, and she insisted he was potty-trained. She asked me to keep him two nights while she was in hospital, and since our sons were close friends at our work's daycare, I was glad to do it.
She sent only a handful of the cheap brand of pull-ups (Fitties?), and the kid was pooping and peeing in them like crazy. He never went anywhere near the bathroom or showed the even slightest indication that he was potty trained in any way. I didn't want to put him back in diapers, but BM's in those crummy little pull-ups were such a mess to clean up! I wound up buying a package of Huggies Pull-Ups and kept him in those until his dad picked him up.
Honestly, she thought that baby was potty-trained, but he didn't seem that way in the slightest to me. A few years later on, I had a big argument with her because she wouldn't allow her children to watch any "commercial" TV (only PBS or educational videos), and my son turned her older kid on to the Power Rangers. LOL!
Some parents go too far over the top.
