Sleep changes and regressions
What people call a sleep regression is usually a cluster of normal changes: more alertness, different sleep pressure, new movement skills, and a baby who is more aware that adults are still nearby 12.
What is probably happening
Many babies sleep differently around this stage because they are developing quickly and becoming more responsive to light, routine, and separation. A rough patch does not by itself mean something is wrong, and one improved night does not mean the problem is solved 23.
The useful question is not "how do we fix sleep forever?" The useful question is "what changed first?" In this age range, the answer is often some mix of a shorter nap, a later bedtime, a feeding gap, a busy day, or a new skill like rolling or sitting that makes settling harder 23.
What to change first
Keep the sleep space simple and safe, keep the bedtime routine short and consistent, and avoid changing several variables at once 13. If you are trying a new nap plan, a new bedtime, and a new feeding pattern all at the same time, you will not know which change helped.
A sensible order is:
- make sure the sleep space is still safe and boring
- keep the routine the same for several nights in a row
- check whether feeding is happening often enough during the day
- adjust naps or bedtime one change at a time
- give the new pattern enough time to tell you something
What not to assume
A short nap, a rough week, or more night waking is common during this window. It is not evidence that the baby is "broken" or that you have missed one magical technique 24.
It is also easy to overread normal development. Babies who are rolling, reaching, babbling, or working hard on separation can sleep differently for a while and then settle back down without any dramatic intervention.
When to hold off on sleep troubleshooting
Do not treat every night waking as a sleep training problem if the baby is sick, feeding poorly, not gaining well, or suddenly much harder to wake than usual 12. In those cases the sleep change is a symptom, not the problem.
When sleep trouble is not just sleep trouble
If disrupted sleep comes with poor feeding, breathing concerns, unusual irritability, failure to gain, or a baby who is harder to wake than usual, call your clinician 12.
If the adults are reaching the point where someone is unsafe to drive or unsafe holding the baby, stop treating it like a pure sleep problem and bring in backup help. The household needs sleep and support.
