Hi,
I'm not a daycare provider but my Aunt has run her own daycare home for 15+ years and has 3 kids of her own. She always had a separate space in the house that was for her kids only. They could keep toys that were just their own in this space and spend alone time alone there as well. She also let her kids pick special activities every week for the daycare kids and let them help her set things up when they go a bit older. HTH!
