Baby sleep, without the stopwatch
When a baby’s sleep pattern suddenly changes
Reviewed
A changed week can reflect development, feeding, illness, travel, teething, environment or ordinary variation. Compare the recent record with the previous few weeks, keep safe sleep constant, and contact your child’s clinician when sleep changes arrive with symptoms or concerns.
Look for the change, not the label
“Regression” is a convenient name for many different experiences. Start with observable differences: more wakes, shorter naps, a later night, new feeding patterns or difficulty settling.
Use ranges that can move
A prediction trained on the last fortnight should change when the baby changes. Gaia does not preserve an old schedule for the sake of consistency; it widens or disappears when recent sleep no longer supports a useful answer.
Know when an app is not the answer
Sleep tracking cannot assess pain, breathing, dehydration, feeding problems or illness. If something feels wrong, use the record to describe the change to a qualified clinician.
