Not necessarily the case, in reference to "push through the kids into the next class so we can get more kids in here." It's because the people who spend 10 hours a day/5 days a week with your kids are creating a structured environment. Which they SO need. The daycare people are attempting to focus more on other kinds of learning and not focusing on so-and-so needs their diaper changed, lets stop the flow of everything here, get interrupted and not complete a project showing you, the parent, what they have been doing all day and what they have been learning. That way, when your children have been potty trained, and put into a different class, you know that they will be getting complete undivided attention from their teachers. These people, chances are, have been doing this longer than you have been a mom, so they know how separating is positively effective. Plus, you signed a form at one point or another and were given tours and given policies in which they regulate and you must abide by. If you don't like their attempts for a structured, educational environment, take them to a different daycare that doesn't care as much, which will probably be easy to find. Or just ask them why they do the things they do. Ask them what they do all day with your kids.
I have heard this too Clunt22. Somehow they associate pooping with a part of themselves but I havent seen that as the issues with my girls. Some of my anxiety about this is also related to their Daycare center that has a strict potty training regiment and doesnt let children graduate out of the "two-year-old room" until they are completely potty trained. I think this is a little silly. My daughters are the oldest and biggest kids in the class (which I am fine with) but the teachers always tell me they are "concerned because they arent trainined yet." What? Really? We cant have the only 3 year olds in the world not potty trained? I think it is more of a "push through the kids into the next class so we can get more kids in here" thing.
I have a 5 and 3 year old who were very different in potty training. My 5 year old potty trained herself at 18 months old. My 3 year old is still having accidents. I talked to my pediatrician about it and she said that sometimes they have an issue with "letting go". They associate poop as a part of them. In my daughters case she would get very upset if I tried to put her on and make her go poop. I would just give it some time. Most kids aren't truly potty trained until 4 or 5. Having them walk around without underwear is a good idea though. hope this helps
