The best antidote to worry is action. If there is an action that will lessen the likelihood of a dreaded outcome occurring, and if that action doesn't cost too much in terms of effort or freedom, then take it. The worry about whether we remembered to close the baby gate at the top of the stairs can be stopped in an instant by checking. Then it isn't a worry anymore; it's just a brief impulse. Almost all the worry parents feel about keeping their children safe evolves from the conflict between intuition and inaction. Your choices when worrying are clear: take action, have faith, pray, seek comfort, or keep worrying.
