M.I.
Hi Sara, I trained my son and my daughter on the little toilet seat that fits right over the regular toilet. I just say keep it simple, let him go on it a few times and when he seems comfortable and knows what it's for then put the cotton undies on him. That's how I did it and it worked. I don't remember how long it took with my son, maybe a few days but my daughter caught on like the first day with a few accidents the first week. I just told her she's a big girl so no more diapers. Good luck in this new adventure!
