In our school there is no rule for being potty trained before the child can be enrolled in the school. We have children who are 3-5 year olds still in diapers. We are also seeing a lot more accidents and children unwilling/unable to change/wipe themselves. I think COVID is partly to blame. Being home and having little or no structure… we try to get kids to change themselves when they have soiled their clothing, but if they are used to having a grown up do it, it can be a struggle. It's especially hard in the older classes because we are fully enrolled and the teachers have a lot of other stuff they are dealing with.
