If your baby suddenly starts waking more often, fighting naps, or refusing bedtime after sleeping well, you’re not alone. A sleep regression can feel exhausting, but it’s often a normal part of your baby’s development.
This guide explains what baby sleep regressions are, why they happen, when they’re most likely to occur, and how you can gently support your child through each stage. You’ll also find links to detailed articles covering each age-specific regression and practical sleep solutions.
A baby sleep regression is a temporary period when a baby who previously slept well begins waking more frequently, taking shorter naps, resisting bedtime, or having difficulty settling back to sleep.
Although the word “regression” suggests your baby is moving backward, that’s rarely what’s happening. In most cases, sleep disruptions occur because your baby is reaching exciting developmental milestones. Their brain is growing, new skills are emerging, and their sleep patterns are changing.
The good news? Sleep regressions are temporary, and with consistency and gentle guidance, your baby can return to healthy sleep habits.
Several factors can contribute to a sleep regression, including:
