J.D.
My daughter was 3 when my son was born, she was trained and went back to diapers. My ped says that being trained will come naturally by the time they enter school. My kids have sensory issues, im having the same problem with my son, he will be 4 in March. He will say he has to go sometimes but mostly he doesnt, he will nly tell me if he poops but not before he sits in it for awhle, i ususlly catch first wind of it though. Its hard to say if theres a biological cause for it. My 9 yr old wets the bed and he will get sudden urges when he cant wait to go, weve had blood, rines tests and other testing done and nothing showed up.
