This is not just shocking and wrong, but also unhygienic...yuck! I agree, this teacher should not be a teacher if this is the only way she could figure out how to handle a problem of a 5 year old pooping in the wrong place. Maybe she's also not allowing the kids to get up and use the bathroom when they need it for all we know. But, EVEN IF the kid was being spiteful and it wasn't just an accident, you don't send his poop home with him! That's when you call the principal in, or a school counselor, and call a meeting with the parents to meet with all of them, or perhaps require the child get checked by a pediatrician. Maybe he's having problems adjusting to school, maybe he has some form of developmental delay that he really isn't fully potty trained, maybe he has some other disability that is leading him to make inappropriate choices (even for a 5 year old), maybe he has a physical problem that he can't control his bowels properly, maybe the teacher literally scares the s*** out of him...who knows, but the solution requires finding out. And, yes, he may need to be held back a year, or put into a special education classroom if he's not at proper developmental milestones or isn't adjusting to the regular classroom.
