Don't use time out specifically but will take a child and put them in an area where they have to play alone with only the things I allow and have to earn the privilege of playing with the rest of the group or a specific toy. Start that right as they join the daycare at a year. Some toys are for chewing and others are not so it starts there. You want to chew you play over here with chewable toys. The rule is simple for older kids if we can't play nicely with our friends we don't get to play with them. I refuse to get into power struggles and for many that is all time out does is cause issues. I just make their lives miserable till they choose to cooperate, lol.
