Why Babies Wake at Night: Biology, Not Bad Habits

Night Waking Is Normal—And Expected

Your baby isn’t broken. They’re human.

Newborns and even older babies wake at night for several key reasons:

1. Feeding Needs

Babies have small stomachs and fast metabolisms—especially in the first 6 months.

2. Developmental Milestones

Learning to roll, sit, or stand can temporarily disrupt sleep.

3. Emotional Regulation

Waking helps babies stay connected to caregivers, especially during phases of separation anxiety.

4. Light Sleep Cycles

Babies spend more time in REM and lighter stages of sleep—which means they’re more likely to stir and cry.

What You Can Do

• Respond consistently and calmly
• Keep the environment dark and quiet
• Offer comfort but avoid overstimulation
• Focus on long-term rhythms, not short-term fixes

Final Thought

Babies wake at night because that’s how they’re wired. And your gentle, consistent presence is exactly what they need.
