I am fortunate enough to have a large separated room that I use for my daycare play space. There are certain items I place in parts of my house such as crafts and small material play so that the older children can play with these items without the young children interfering. I use a child size picnic table in my kitchen for these items. It allows the children to enjoy legos, older child games with dice, and other items that are not appropriate for small children. This way the older children can enjoy what they like and not restrict their play.
