I guess you have to embrace those wonderful moments until he becomes more stable. It sounds like you handled it well.
My ex seems to be reconnecting with the kids more and more. First it was my son, then my oldest daughter, and now my youngest daughter. His interactions appear much more sincere compared to when he was in the middle of his crisis. I pray that this will continue. You never know when things will change.
