How Long Should You Swaddle a Baby Each Night?

July 6, 2025

Swaddling is one of the most recommended newborn sleep techniques — and for good reason. It helps babies feel secure, mimicking the cozy feeling of the womb, and can reduce startle reflexes that disrupt sleep. But a question many new parents ask is:
"How long should I swaddle my baby each night?"

Let’s dive into what the experts say about the safe duration, age limits, and best practices for swaddling your baby through the night. 💡

🕒 How Many Hours Can a Baby Be Swaddled at Night?

In general, it's safe to swaddle your newborn for long nighttime stretches — up to 8–10 hours — as long as:

The swaddle is secure but not too tight
Baby is always placed on their back to sleep
Baby isn’t showing signs of rolling over

Newborns sleep a lot — often 14–17 hours a day, including naps. That means they may be swaddled frequently. Nighttime swaddling helps support longer, more restful stretches of sleep for both baby and parent.

✅ Rule of thumb: Swaddle your baby at night until they begin showing signs of rolling over, which usually happens around 8–12 weeks.

📆 When to Stop Swaddling at Night

It’s important to transition out of the swaddle once your baby begins showing signs of rolling from back to stomach. This is a major safety consideration — once a baby rolls over while swaddled, it can increase the risk of SIDS (Sudden Infant Death Syndrome) or suffocation.

Signs it’s time to stop:

Baby is around 2–3 months old
Baby starts breaking out of the swaddle
Baby shows signs of rolling over (even if they haven’t done it yet)

At this stage, it’s best to move to a sleep sack or wearable blanket that allows arms and legs to move freely.

💤 Should You Swaddle During Naps Too?

Yes! You can swaddle your baby for naps during the day if:

They’re still under 3 months
They haven’t begun to roll
They sleep better and more soundly when swaddled

Just like at night, always lay your baby on their back and avoid loose bedding or soft objects in the crib.

❌ Risks of Swaddling Too Long

Swaddling past the recommended age or for too many hours without breaks can cause:

Restricted movement, affecting development
Hip dysplasia, if swaddle is too tight around the legs
Overheating, especially if room temperature or clothing layers are too warm
Delayed transition to self-soothing sleep habits

💡 Always follow safe sleep guidelines and give baby some "unswaddled" awake time during the day to stretch and move freely.

🧣 Best Practices for Overnight Swaddling

✅ Choose a breathable swaddle made of cotton or muslin
✅ Ensure it’s snug at the torso but loose around hips and legs
✅ Dress baby appropriately underneath (based on room temperature)
✅ Always lay baby on their back
✅ Stop swaddling once rolling begins

👶 Transitioning Out of the Swaddle at Night

When it’s time to stop swaddling, many parents worry about disrupted sleep. Here’s how to make the transition smoother:

Swaddle with one arm out for a few nights
Then both arms out, keeping the wrap around the torso
Gradually switch to a sleep sack with more freedom
Stick to a calming bedtime routine to signal sleep
Be patient — a few nights of adjustment is normal!

✅ Final Thoughts: Swaddle Smart, Sleep Better

Swaddling is an amazing tool to help your newborn sleep better — but timing matters. While it’s safe to swaddle for most of the night during the first few months, it's essential to transition as soon as baby starts trying to roll.

By swaddling safely, consistently, and mindfully, you're giving your baby the best start for restful, secure sleep.
