What not to change during a regression
Everything has fallen apart and the urge to change something - anything - is overwhelming. This is the moment when changes do the most damage, and it is worth knowing which ones.

During a developmental disruption, your baby is already dealing with a system in flux. Adding a change of method, room or schedule on top gives them two new things to adapt to at once, and gives you no way to tell which one caused what.
There is also a second cost that shows up later. Most of the lasting damage from a bad fortnight is not the fortnight itself - it is the new habit introduced during it and never removed afterwards.
Do not change these
The settling method. Starting or abandoning any structured approach mid-disruption. Whatever you were doing, keep doing it.
The room. Moving out of your room, into a sibling’s room, or to a bed. All of it can wait six weeks.
Night feeds. Neither the moment to start weaning nor the moment to add feeds you had stopped. Both decisions will be clearer in a month.
The nap schedule. Dropping a nap in response to two weeks of refusal is the classic expensive mistake, particularly around twelve months.
Cot to bed. Never during a disruption, and preferably not before three unless they are climbing out.
What is safe to adjust
Bedtime, earlier. Almost always the right lever, and almost always underused. An overtired baby handles a developmental leap much worse than a well-rested one.
Wake windows, in fifteen-minute steps, if the current ones have clearly stopped fitting. Daytime support for whatever skill is being learned - more floor time, more practice, more hiding games. And extra comfort at night, provided it is comfort you can keep offering after the disruption ends.
That last distinction is the whole trick. Staying longer at bedtime for a fortnight is fine. Reintroducing a feed to sleep you removed three months ago is a decision with a much longer tail.
Extra comfort is free. A new sleep condition is a loan, and you repay it later.
Holding your nerve
The hardest part is that doing nothing feels like doing nothing. It is not - holding a routine steady through a fortnight of disruption is active work, and it is what determines whether you come out at the same place you started or somewhere further back.
Agree with the other adults in the house what you are and are not changing, in daylight, before the night starts. Decisions made at 2am are not decisions.
Keeping a record of what you loosened
During a bad fortnight it is genuinely difficult to remember what you have started doing. Extra feeds, staying in the room, an earlier bedtime, a nap in the pram, someone sleeping on the floor - these accumulate one night at a time and none of them feels like a decision.
Keep a short list on your phone as you go. When the disruption ends, that list is exactly what needs undoing, in roughly the order you added it. Without it, most families discover their new arrangements only weeks later, by which point each one has become established and has to be dismantled properly rather than simply stopped.
Where the pressure to change comes from
Mostly from exhaustion, and it is worth naming because it is the mechanism rather than a character flaw. After five bad nights, doing something feels essential and doing nothing feels like negligence. That is the state in which people move rooms, drop naps and abandon methods, and none of those decisions survive scrutiny in daylight.
A useful rule: no structural change gets decided in the week it is first considered. Write it down, wait seven days, and look again. Most of the ideas that seem urgent on night five have evaporated by night twelve, which is exactly the point.
When to stop troubleshooting
If a baby is unwell, in pain, feverish, or not feeding properly, none of this applies - treat the health issue and let the routine go for as long as needed. Any red flag means a GP or health visitor, not a firmer schedule.
