I have a student who is delayed. He is 3, and not yet potty training. At home parents have been working on it, and I really encourage it at school. He is in daycare for most of the day and they are working on it as well. Sometimes he wears underwear, but other times the mom sends him in a pull-up. He has only had an accident at school once (pooped) and has never had an accident at daycare. Today, he even told me he needed to use the bathroom when asked. He goes willinging and seems to enjoy the bathroom. The problem I am having is that mom has been switching between underwear and pull-ups. Some days he has underwear and others pull-ups. When he wears the pull-ups, he doesnt want to use the bathroom and will not go willingling. When he is wearing underwear, he goes in the bathroom. After 2 weeks of wearing underwear, he came today in pull-ups. I have extra never used underwear in case of emergencies and I switched him into the underwear. He kept tugging at the pull-up and was not happy about having to go use the bathroom. Why do I feel like I am at war with the parents on potty training? I want their child to succeed, not keep regressing. Anyone have suggestions on how I can approach this parent or should I leave the potty training issue to myself? I am a public early childhood classroom.
