Well done, Kimm. Keep us posted on all the great connecting work you are doing.
One more thought… It’s ok if your son gets upset about the timer. That can be an opportunity for you to simply set that little limit, and STAYLISTEN to his feelings.
You say gently and kindly, “yes, we’re going to use the timer, sweetie” and you can move toward the timer, without actually setting it or forcing it. If he is getting upset, it’s really ok to slow down and simply listen.
He is using the timer as a PRETEXT to offload some tension and fear. This is a great opportunity, because on the surface, the timer has nothing to do with separation. But the timer does stir up the same feelings. If you listen to him release feelings about the timer, I suspect that separating may start to go a little easier.
Does that make sense?
Peace & Smiles,
