Hi Joe, Its hard to decide on which diapers would be best for your son. If he is a heavy wetter you might want to try cloth diapers and plastic pants instead of goodnites. Goodnites tend to leak if the child wets a lot. If you want to stay with disposables you might want to try a small adult diaper for him. Has your son had a preference toward cloth or disposables? Will you be changing his diapers also? I would be more than happy to discuss which diapers might work best for you. I have a cousin that has been in diapers for a long time.
