K.G.
For my first son, we put them in a baggie and had him say goodbye to them and he threw them away. I took them out of the trash as soon as he left the room in case he ever had a melt down (I hid them up high were he would never see), but he never asked for them again. With my second son a friend of mine came over with a younger baby and I told him that he needed his "chomper" because he didn't have any. He gave it to his mom and she pretended to take it with her when she left. He asked for it that night and said we needed to call her to get it back. When I told him it was too late at night he was ok with that. Good Luck.
