The five bedtime steps that cannot be done out of order
TEETH, TWO BOOKS NOT ONE, CURTAIN OPEN A BIT, LANDING LIGHT ON, SAY IT BACK — numbered, and IF YOU GET IT WRONG START AGAIN underneath, meant.

Five steps, numbered. TEETH. TWO BOOKS NOT ONE. CURTAIN OPEN A BIT. LANDING LIGHT ON. SAY IT BACK. Underlined beneath: IF YOU GET IT WRONG START AGAIN.
Skip step three and go straight to step four, and you will be doing step one again. This is not a threat. It is how the routine actually works.
Why does the order matter more than the steps themselves?
Because the order is the point, not the individual jobs.
Teeth, books, curtain, light, the same words back — none of these is difficult on its own, and a parent doing them out of sequence has still, technically, done everything on the list. It doesn't count. The five steps in the same order every night are the one part of the day that behaves exactly the same way it did yesterday, in a day where school, dinner, who's picking up whom and what mood everyone arrived home in were all different. The ritual is the reliable object; the individual tasks are just what it's made of.
Is "start again" actually enforced, or is that a joke?
Enforced. Get step three wrong — curtain open too far, or not at all — and the whole sequence restarts from teeth, and the child will notice and insist.
It looks stubborn from the outside and it is not: this is one of the only places in a small child's day where they get to set a rule and see it actually hold. Bedtime, unlike almost everything else that happens to them, is negotiable from their side. Getting it wrong and having to start again is the proof that the rule was real in the first place, not decoration.
Why print the numbers instead of a soft bedtime scene?
Because the numbers are the actual subject and a moon-and-stars illustration would be about bedtime in general, which nobody in this house is living through.
A drawing of a sleepy child under a blanket could belong to any family with a bedtime. Five specific words, in this order, with STAY AGAIN meant literally underneath, belongs to exactly one household on exactly one landing. Line art in a single colour suits this kind of list well — chalk-board lettering, hand numbered, nothing decorative competing with the words for attention.
Whose rules are these to print?
The household's. Nobody invented "two books not one" or "landing light on" for anyone else to license — it's five lines a specific child assembled and started enforcing, and the only decision left is whether the child, later, wants their own bedtime list read back to them on a shirt. Some will. Ask when they're old enough to answer, rather than guessing on their behalf either way.
Does every household have a list like this?
Most that have got a small child through bedtime for more than a few months do, and every one of them is different.
Some run to three steps, some to eight; the order of a stranger's five would mean nothing printed on your own shirt, because the whole design depends on it being the actual sequence enforced in this house. What travels is the format — numbered steps, a line that's underlined because it's meant — not the specific five words. What a household never wrote down anywhere else is the same kind of object: knowledge that only exists because somebody who lives there could recite it.
What if the routine has already stopped?
Print it anyway — the stopping is information too, not a reason to leave it out.
Routines like this one usually end the way most small-child systems end: quietly, over a week or two, without anybody deciding out loud that it was over. One night book three doesn't happen and nobody insists on starting again, and that's it, permanently. A shirt made after the fact is a record of something that was strictly enforced for a specific stretch of years and then simply wasn't any more.
Does it print well?
Yes — the chalk-board lettering and the numbering are doing the work, so keep both plain.
Five short lines set in one hand-lettered weight, numbered down the left, read clearly at chest size in a single ink on a dark garment — navy or black both suit it, since chalk-on-slate is the reference the lettering is already borrowing. The underline on the last line is the only emphasis the design needs; adding a border or a chalkboard frame around the whole thing turns it into a picture of a sign rather than the actual list.
How do I get one made?
Describe the routine at JustOG — the steps, in order, and which one gets you sent back to the start. Pick a direction, drag the crop frame, see it composited on the real garment, and it's made to order and shipped.

Step three, tonight, went fine. Nobody had to start again.
