[ on learning parenting skills] It all just goes by so quickly that you really are just reacting to emergencies. Just like all of those other middle-class parents, I worried. I like to say there should be a worry bank for parents so that all things you worry about that don't happen could be deposited in the worry bank, and the next time something happens, you wouldn't have to worry about it. I certainly would have had a substantial account in the worry bank.
