I totally understand what you mean about not being able to leave. DS & I can virtually always leave a situation, but on occasion, I work at a church nursery, with DS, and since I'm the paid help, I can't leave if he's unhappy, etc. When this has happened, I redirect him and take him and play one-on-one with him somewhere else in the room. Sometimes, that can be rough, too, though, since, as I said, I'm the paid help, and it looks like I'm getting paid to watch my kid by himself. Sometimes, when I redirect, I take DS to play near another child who doesn't cause as many conflicts, or rather who doesn't have a conflicting personality with DS.
