I realize the K teacher will not have time to do this with 20 children in a class, but my 4.5 year old DS cannot (will not) wipe his own tush after poop. He has tried, so I give him some credit for trying, but he mostly misses, we have tried mirrors, etc. The school year is coming up quickly... Do the teachers help with this issue? And why does it seem that have I had every potty training issue out there???
