So I babysit a kid who is 4 and he is still not potty trained.. Is this normal? I know all kids learn at different times but he is a smart brave child! I feel that the parents just aren't focusing enough on him. They are a beautiful family!! I just don't know how to address this.. Changing a diaper on a 4 yr old is a bit ridiculous to me.. Thoughts? I'm definitely not bashing the parents!! Although I have just started out with children so maybe I just don't know enough.
