Our first law of parenting: if you are doing something even remotely dangerous in or near your house, the children will feel an insuperable need to be in that place and, ideally, under your feet or between your legs.
Our Second law: Coincidentally, if children are asked to perform a task that feels too much like work, even if it is a task they would normally do for entertainment, the children will discover an urgent need to be somewhere, anywhere, else doing something, anything, else.
Resulting parenting tip: Maximize child safety when using bleach, frying, mowing the lawn, chopping wood, etc. by giving each child a task. Put the toddler in charge of the deep fryer. Hand the little one an axe. Set up a step stool next to the grill. Buy a pink chainsaw bedecked with unicorns. They’ll do it for a minute or two and then disapparate to points unknown. The result will be a safer home for them and a calmer workspace for you.
