After a child is done raging is a great time to work on attachment. They are generally emotionally exhausted and calm. It is a good time to rub their backs if they have gone to lay down somewhere. If they will allow it pull them onto your lap and have a Snuggle Time (see labels at right) It is a time for reassurance:
"You sure had a lot of anger (fear, sadness) today". "You will learn to use your words as you being to heal" "I am never going to leave you." "I'm so glad I am your mom."
You get the idea. Love them when they have been most unlovable.
