My 4 year old Nephew was over yesterday and I noticed he didn't go to the toilet the whole 4 hours he was here.
I asked him if he needed to go potty and his mom said that he was wearing a diaper and not potty trained?
She said that hadn't even tried and he'll use the toilet when he's ready?
He's already 4 years old and will be entering kindergarten next year.
He should be ready by now.
