BABY SHOWER/DIAPER SHOWER IDEAS

Annabel • "For this child I have prayed..." 🛐✝
So, I'm registered at Walmart and Target. I'm sending out Facebook invites along with actual snail mail invites. My question is, how do you word it as to where we are registered. And also, my husband is having a "diaper" party the same day, but idk how to word it for people to bring diapers. Like I don't want them to feel obligated to bring diapers or buy a gift,  but I also don't want to have any diapers and have to buy everything ourselves. I heard something about a diaper raffle but idk how to do that. Help please! :)
