Overtiredness can fragment sleep
When sleep pressure becomes messy, babies can wake more often rather than sleep more deeply.
The bedtime association may be very strong
If your baby falls asleep with feeding, bouncing or rocking every time, they may call for it after each cycle.
Discomfort matters too
Teething, reflux, illness, temperature and environment can all contribute. If something feels off medically, get it checked.
Look at the whole day
Total naps, timing of the last nap and bedtime all affect how the night unfolds.
Important: baby sleep varies enormously. Avoid one-size-fits-all promises, and always prioritise feeding, growth and safe sleep advice.
Safer sleep reminder. For babies, use a firm, flat sleep surface and follow the latest safer sleep advice from the NHS and The Lullaby Trust.

Can teething cause hourly waking?
Sometimes, yes, but it is rarely the only reason for weeks on end.
Is this always a sleep regression?
Not always. Regressions exist, but so do timing problems and associations.
Where should I start?
Start with the first bedtime of the night and the last wake window.
