Kindergarten bathroom accidents

Ri

I'm getting exhausted from my five year olds accidents. He wets the bed a pullups with sposie inserts doesn't hold all fluid and matter. He has to shower then and it means less sleep for him. All his bedding daily has to be washed. At school he has had 3 accidents in six days of school.

I have him enrolled in PT but that hasn't started yet. As a mom I'm exhausted but worried. What else can I do? The issue is both #1 and #2.
