Erinn, I also wouldn't go too crazy on purchasing items for the daycare - wait till you see garage sales, and you'd be surprised what people get rid of!

Like Mimi, I ask parents to provide certain items: Playpen, bedding, extra clothes, diapers, wipes, etc. I do provide cots and booster seats. We don't have a lot of space in our home, so think storage and what you want to see when you're on holidays etc! lol
