I have daycare toys that everyone can use and I have toys just for my kids (bday presents,xhristmas presents etc.)

This way I avoid many fights lol

However their personal toys either stay in their room, or in their half of the playroom.
I sectioned off a part of the playroom just for them since as the moment all my daycare children are much younger than them and always want to follow them around

So far so good !
