The Real Reasons Your Baby Won’t Sleep (Backed by Science)
1. Your Baby Is Overtired (The Most Common Cause)
Pain
Your baby rubs their eyes, cries harder, gets hyperactive — yet still refuses to sleep.
Insight
Research shows that when babies stay awake too long, cortisol spikes → wired, restless baby.
sleep studies reveal 60% of sleep resistance is linked to overtiredness.
Solution
Follow wake windows, shorten awake time by 10–20 minutes, start bedtime earlier.

Example
A 4-month-old should stay awake 1.5–2 hrs max.
2. Baby Is Undertired (Not Sleepy Enough)
Pain
Baby kicks, rolls, laughs — but won’t sleep.
Insight
Not enough “sleep pressure” = no melatonin release.
Very common with long, late naps in Mediterranean families.
Solution
Increase wake time 10–30 minutes, add calm stimulation, avoid late naps.

Example
Nap 5:00–6:00 PM → bedtime shouldn’t be 7:00 PM.
Try 8:00–8:30 PM instead.
3. Feeding Issues (Hunger or Discomfort)
Pain
Baby sleeps then wakes crying shortly after.
Insight
Gas, reflux, hunger — top sleep disruptors.
Light reflux causes fragmented sleep even if baby looks “fine.”
Solution
Full feed before bed, upright 10–20 minutes, slow bottle feeding.

Example
Add a dream feed at 10:30–11:00 PM for babies waking every 40–60 min.
4. Too Much Stimulation Before Bed
Pain
Baby calm… until you try to put them down → meltdown.
Insight
Screens, bright lights, loud noises = adrenaline spike.
Babies exposed to screens take 22–34 minutes longer to sleep.
Solution
Stop screens 90 min before bed, use dim lights, soft routines.

Pain

Insight
Regressions happen during skill development.
Solution
Keep routine stable, give comfort, increase day sleep slightly.

Insight
Temp, light, and noise deeply affect melatonin.
Solution
Blackout curtains, 19–21°C room, white noise.
