What you did sounds great OP! We call it "taking a break" and I think it's very healthy to take a break and regroup when feeling overwhelmed/angry, etc.

Wanted to add I find traditional time outs sad b/c of really the "love withdrawl" concept of them (Alfie Kohn's term). The if you can't behave like I think you should, you don't get to be around me. It misses IMO both an excellent teaching opportunity, and creates distance in the relationship.
