Be careful in treating your own child different than the daycare children in the sense of timeouts in their room. The others don't have to go to their room so why do they have to. For sure this should be the last resort option and mostly they do time outs in the same timeout spot as the others. We can sometimes be the one escalating behaviour because they are truly angry with what they feel are injustices and favourtism. Especially if your child is an only child they haven't learned group dynamics any more than if you took an older child into care because Grandma no longer wants to cater to them and we all know how annoying they can be.
