Kid loves his diaper

My five year old son is already potty trained, but he refuses to give up the diaper. He never goes in his diaper. It's almost like a security blanket and I don't know what to do. I've tried giving him boxers and briefs but he refusing to wear them and even if I try to trick him in them, he finds out and throws a tantrum. I hid the diapers from him, but he finds them and puts one on. I have to have diapers in the house since I also have a 1 year old. What do I do to get him to wear the underwear and not waste the diapers?

Perhaps there are some jealousy issues because your youngest 1 year old wears diapers.Maybe you will have to get tougher ignore a tantrum he will throw he is doing that as he knows you will relent and let him wear them.,have a talk to him, tell him no more diapers then let it go, if a big issue is made of it it will continue, its in your hands to set the bounderies.Focus on his positive side , give him plenty of attention, get Dad involved with outside games and Fun,he could be feeling left out if he sees his younger sibling getting more attention,
