Desperately in need of potty training advice! My 3.5 year old pees in the toilet, wears underwear all day even to bed and stays dry through the night but he absolutely refuses to poop. He will bring me a diaper to put on him, poop, get cleaned up and put underwear back on. If I refuse to put a diaper on him he will hold it until I do and get constipated because of holding it. He has a nervous breakdown if I sit him on the toilet even though he has a toddler seat. His occupational therapist said its normal and to cut a hole in the diaper so he has that feeling of comfort but how can I when he wont even sit? He starts school in September and I'm starting to get really stressed about it. toddler wears for flower girl
