Diaper raffle

My husband and I are expecting baby #2 this summer and decided we want to have a “Baby-Q”. We still have all of the big baby items from our first so we’re not going to register for anything, we just want to get together with friends and family to celebrate. We would like to do a diaper raffle - it never hurts to have more diapers! The party will be co-ed so I’m trying to think of some fun prizes. If anyone has any ideas they are more than welcome! I don’t know why but I’m struggling 🤣
