I know this thread is a little old now but thought I'd offer another option which I've found really useful. It's called "Time In". If you look for the Circle of Security website and under resources you can download some fantastic stuff, including a 'Time In' guide. Basically it involves being with your child during the time in and helping them identify and talk through feelings; take responsibility; and discuss ways of responding to the situation in the future. Obviously it depends on the age of the child as to how you implement this.

BTW - I don't think time out is inherently 'bad' and it definitely has a place when we (the parent) are too frustrated to deal with the situation effectively anyway. It's all in how we implement these strategies and how our children (and we) feel when it's happening that counts.
