Why doesn't baby sleep at night? 5 most common reasons
⚡ Short answer: At 5 months, frequent night waking usually stems from hunger, 4-month sleep regression, teething, developmental leaps, or environmental differences; waiting 2-3 minutes before responding sometimes lets them self-soothe.

My 5-month-old won't sleep at night, constantly waking. Why don't babies sleep, what are the most common reasons?

Frequent nighttime waking at 5 months is very common. Usually it's not one single cause but several factors working together:
- Hunger: A 5-month-old's stomach is still small and he may feel hungry at night.
- Sleep regression: Around 4 months, babies' sleep cycles start resembling adults'. Every 45-90 minutes they enter light sleep and wake until they learn to fall back asleep.
- Teething: Some babies start teething around 5 months; sore gums can disrupt sleep.
- Developmental leaps: Learning new skills (rolling, reaching) — his brain processes these even at night, causing waking.
- Environmental changes: Room temperature, noise, light, clothing — small differences can wake him.
A helpful tip: Instead of picking him up right away, wait 2-3 minutes — sometimes he'll settle back on his own. Check if daytime nutrition is adequate. If this goes on longer than 2 weeks or baby becomes increasingly uncomfortable, consult your pediatrician. I know you're exhausted — you're not alone.
