M.H.
when my daughter had a bad dipper rash i would put her in her play pin with a towel down under her feet to catch the pee... I know yours is a boy but it is just a thought... Now I also used A&D on her when she did have to wear a dipper because she was really raw and it really helped keeping the area dry... there are two type one is just the ointment and the other is the cream... I hope this helps
