The daily routine of a 12-month-old
One year. Your child’s cycles have lengthened, their sleep looks more and more like yours, and the daily routine has been stable for months.
It is also the age where you will be told, often with great confidence, that "at one year you go to one nap". That is wrong in the vast majority of cases. The transition happens between fourteen and eighteen months, and bringing it forward by three months is paid for in broken nights.
What does appear, on the other hand, is character. The first resistance at bedtime has nothing to do with sleep, and is handled differently.
