Many families notice small improvements within the first few nights, especially with overnight sleep. More consistent and lasting changes often develop over 1–2 weeks. It can take up to a month to see full improvements, particularly when it comes to naps.
We generally recommend focusing on overnight sleep first, as nighttime sleep tends to consolidate more quickly due to stronger sleep pressure and circadian rhythms. Once overnight sleep has been underway for about a week and feels more settled, families can begin applying the same approach to naps.
Every child is different, and factors such as age, temperament, consistency, and prior sleep habits all play a role in how quickly changes occur. Progress is rarely linear, and gradual, steady improvements are both normal and expected.
