My son is 5 years old and he will starting school in 2 weeks.. He's still not fully potty trained yet, he wears underwear in the daytime and he sleeps in an overnite pull up.. I've tried everything i don't know what else to do he will sit on the toilet for an hour and he won't do nothing. When get's up i say about 10 minutes later he pisses everywhere!! Please help.. His father isn't in the picture so it's just me, my mom, and my sister. I will not keep him out of school and he has to have speech therapy.
