The 12 month regression and the nap confusion
Your one-year-old has started refusing the morning nap and waking at night, and the obvious conclusion is that they are ready for one nap. That conclusion is the expensive mistake of this month.

Around twelve months there is a large developmental cluster: walking or nearly walking, first words, a jump in comprehension, and often molars. All of it disrupts sleep, and the disruption shows up in naps first because naps are the most fragile sleep of the day.
The problem is that the pattern - refusing the morning nap, difficulty settling, waking at night - looks identical to the start of the two-to-one nap transition. And most children are not ready for one nap until somewhere between fourteen and eighteen months.
How to tell them apart
Duration. A leap resolves in two to four weeks. A genuine transition builds steadily over a month or more and does not resolve.
The afternoon. A child falling apart at four o’clock without the morning nap is not ready to lose it.
Nights. Leaps disturb nights as well as naps. A nap transition is largely a daytime phenomenon until it starts causing early waking.
What else is new. First steps, a language burst, molars. If you can name the new thing, it is a leap.
What not to change
Do not drop to one nap. Keep offering both, and if the morning nap is refused three days running, cap it at thirty minutes rather than removing it - a shorter morning nap often restores the afternoon one without leaving your child awake for six hours.
Do not change the settling method, move rooms, or start night weaning during this window. And do not respond to night waking by reintroducing something you stopped months ago, unless you are content to keep doing it after the leap has passed.
At twelve months, a refused nap is a new skill demanding rehearsal - not a schedule announcing itself.
What helps
Enormous amounts of daytime practice for whatever is new. A child who has spent an hour walking up and down the hallway is less compelled to practise at midnight. Early bedtime on the days a nap is genuinely lost. Extra patience at bedtime, and the same bedtime sequence regardless.
Two to four weeks is the usual span. If it has been six weeks and the pattern is consistent rather than spiky, then it may be a genuine transition after all, and that is a different piece of work with a longer timetable.
Riding it out without changing anything
This is the month where holding still is most valuable and hardest. Everything invites intervention: the refused nap, the new night waking, the bedtime that has doubled in length. The temptation is to restructure the day, and the restructure is what turns four bad weeks into three bad months.
What to do instead is unglamorous. Keep offering both naps at the usual times. Cap the morning one if it is eating the afternoon. Bring bedtime forward on days a nap is lost. Give whatever is new - walking, words - as much daytime practice as you can manage. Then wait, and check again at four weeks rather than at four days.
Cot safety at twelve months
A newly walking child is a newly climbing one, and this is the month to check the cot again. Mattress at its lowest setting, nothing in the cot they can stand on, nothing within reach from a standing position - cords, cables, shelves, furniture beside it.
This is also the age where a small comforter becomes reasonable, once they are over twelve months. Keep it small and breathable, with no ribbons or loose parts, and buy a second identical one for when the first goes missing. It is a genuinely useful thing to have during a leap.
When to stop troubleshooting
Fever, ear-pulling, refusing food as well as sleep, or a child who seems unwell rather than busy, mean a GP appointment rather than a schedule discussion. Loss of skills or language is worth raising promptly with your health visitor.
