Quote from a retired Disney princess, who was one of the first Snow Whites. When you are hugging a child, always be the last one to go. You never know how long they need it. Sometimes even us 'big kids' need those hugs , too.
Listen earnestly to anything your children want to tell you, no matter what. If you don't listen eagerly to the "little stuff" when they are little, they won't tell you the big stuff when they are big; because to them, all of it has always been big stuff.
