The summer we turned "get taller" into a daily routine
Half a centimeter in the first half of the holiday. Almost three in the month after we changed the plan.
This one is ours. ChildStep was built in a house with two daughters in it — Hannah, thirteen, and Katie, nine — and in the summer we were building it, Katie wanted one thing: to be taller. She was 135.5 centimeters. It became a family goal, and then it became a daily routine, which is the half nobody warns you about.
It was written down with a date on it, with Hannah on it too, and then broken into what would actually have to happen. A glass of calcium milk every evening. Exercise, daily. Each part went to a named person rather than to the household — not a chore chart on the fridge, a plan with owners — and the girls marked their own off.
Half the holiday went by and she had grown half a centimeter. It would have been easy to read that as a child who had not tried hard enough. She had tried, and the record was there in her own hand, so that argument never got started. What the record could not tell them was why, and for that they had to look outside the app: the meals were not built the way they had assumed, and she was short on both calcium and vitamin D3.
So the plan changed, and it changed in front of her. The meals were rebuilt. Vitamin D3 went in as a step of its own, for both girls, with a morning reminder — because the mornings it had been missed were not mornings anyone decided against it, they were the mornings everybody was in a rush. The milk stopped being some time in the evening and became a fixed hour. The exercise stopped being a token ten minutes and became jumping rope, hard enough to be out of breath, first as a skill to learn and then as a number to hit.
One part of the plan never became a step at all. Bed before ten, awake before seven — that was settled in this house years ago, and it may be the strongest lever of the three, since a child does most of their growing in deep sleep. It did not need an app, because nothing that already holds does. ChildStep is for the part of a plan that has not become a habit yet.
The rest is less glamorous than it sounds. A day marked missed and a day marked skipped are not the same day, and the summer turned on the difference: the weekends nobody jumped rope were mostly the weekends the four of them were out walking the pedestrian streets and coming home with books — a different kind of exercise, not something to feel bad about.
The two are counted apart in Insights, and Lookback sets a month beside the one before it, so when the family sat down they could tell a busy week from a broken plan. The first time they looked, it was the plan.
In the month and a bit that followed, she grew almost three centimeters. She is 139 now.
Hannah’s summer looks nothing like her sister’s. She came to the milk two months later, gave her evenings to a guitar, and moved her rope sessions far more often. Both sit inside the same goal, side by side, and neither was ever held up against the other. That was deliberate.
Three and a half centimeters over a summer is not a number that will impress everybody, and we are not going to tell you an app produced it. Children her age grow five or six centimeters a year with nobody helping at all, nine is around when girls can start growing faster on their own, and a family has no control group — you get to run the experiment once, on the child you love. What we would stand behind is smaller and more repeatable than centimeters: halfway through that summer this family could see that what they were doing was not working, and had something specific enough to change instead of a feeling that somebody should try harder. The notes they left at the end of that month are not encouragement — they read “Hannah’s milk did not start until the 25th. That was on us, not on her,” and, under the sprout, a reminder to measure again at the end of September and not before. That is what a summer routine costs to keep once the first enthusiastic week is over. Paul, for the record, put his own name on the family reading goal beside Katie’s, at the same nightly hour. She finished far more evenings than he did. He left his name on the list anyway.
