The shoes, the zip, and the cereal
It's quarter to eight. Ava is four and she's sitting on the bottom stair with one shoe on the wrong foot and the other shoe in her hand, looking at it as though it's arrived from somewhere. You've asked her twice. You're standing in the hall with your coat on and your keys in your hand, and the thing that happens next is so quick you don't notice yourself deciding it. You crouch, you take the shoe, you swap the wrong one over, you do both straps, and you're at the door in twenty seconds. She didn't object. Why would she.
Upstairs, Leo is nine and his school bag is on the landing where he left it, and you know without looking that the reading book isn't in it and the water bottle is still in the sink. So you put them in. You've been putting them in since he was five. At the kitchen table, Maya is fourteen and she's got a form for a trip that needs a signature and a phone number and the name of a doctor, and she's held the pen for a minute and then said "can you just do it". You did. It took you forty seconds and it would have taken her ten minutes, most of which would have been asking you what to put.
These are invented, but I'd guess yours are close. Notice the shape. There's a job. The child could do it, badly and slowly, or could learn to. You do it, well and fast. Nobody argued. Nothing went wrong. The morning worked. And the same three jobs are waiting tomorrow, because nothing about this morning changed who can do them.
Some words. The takeover is the moment your hand goes to the job and finishes it. The hand is the reflex itself, the hand that's already moving before you've decided anything. The quick version is the job done by you in a fraction of the time. The slow version is the job done by the child, badly, at three times the length. The go is the child's attempt, whatever it produces. The margin is the extra minutes the slow version needs and the quick version doesn't. And the least help is the smallest thing you can do that keeps the child's hand on the job, which chapter 8 is about.
I'll use "badly" throughout, and I mean it kindly. Badly is the standard every first attempt meets. The shoes on the wrong feet are a bad job, and they're also the only job a four-year-old can do, and the one that comes before the good one.
Before you go on, do one thing. For a week, count the takeovers. Every time your hand goes to a job the child could have had a go at, make a mark, and next to the mark write roughly how long you saved. Most parents who do this get a large number of marks and a small number of minutes. That's the shape of the habit, on paper, and it's worth seeing before I argue with it.
