...we bought so much safety gear for the house. News days with stories like this make me go cold inside. Only now are we slightly dialing back the freak-out when Noodle gets out of our sight outside the house for a moment or two, even though I can distinctly remember being five and spending hours thrashing around in snowbanks, making forts and having a grand old time by myself.
I don't want to speculate about the circumstances in this case - it suffices to say it'll send you flying down to the store for doorknob safety covers, especially if you've got kids with the wandering bug.
