According to my childrens doctor yes it is normal children sometimes help each other in the bathroom clean up and hey wow theres a hole with gook in and around..... well you see where Im going. its normal for this to happen with my children more than once lol

my suggestion is if you are still having a problem with this talk with your treatment providers or a mental health treatment provider and your medical doctor they will explain to you whether this was normal directly related to your problems.
