We’re diving head first into summer, and the temps are rising faster than my blood pressure after my mini poodle chews up another pair of shoes.
And now that we’re seeing higher temperatures, you might be wondering how to keep your baby cool and comfortable at night.
The good news? I’m here to help! Today, I’m sharing 3 ways to practice safe, and cool, sleep during the warmer months.

Why Temperature Matters & AAP Recommendations
Studies cited by The American Academy of Pediatrics indicate an increased risk of Sudden Infant Death Syndrome (SIDS) in babies who are overheated.
The organization recommends the following when it comes to safe, cool sleep:
- Infants should be dressed appropriately, “with no greater than 1 layer more than an adult would wear to be comfortable in that environment.”
- Parents should be on the lookout for signs of overheating, including the infant’s chest feeling hot to the touch or heavy sweating.
But what are some ways you can ensure your infant stays cool and comfortable while they sleep? Keep reading!
Cool Sleep Tip #1: Use a Muslin Swaddle Blanket
I typically recommend parents of newborns swaddle their babies–especially during the first few weeks.
Swaddling mimics the cozy environment of the womb and is often comforting to newborns.
However, many parents are worried that their baby will become overheated in a tight swaddle–especially in the warmer months.
Enter the muslin swaddle blanket: the fabric is thin, light, and breathable, but still offers the comfort of a traditional swaddle blanket.
Aden + Anais, a very popular baby brand, offers muslin swaddle blankets in a variety of prints, but Amazon carries several other brands as well.
Halo also makes a Muslin sleep sack for older babies who have transitioned away from the swaddle.
Cool Sleep Tip #2: Hang Blackout Shades
If your little one’s room has a lot of natural light, consider hanging blackout shades or curtains.
Sunlight can drastically increase a room’s temperature, so keep those shades down or curtains drawn all day to keep the room nice and cool for sleep time.
Cool Sleep Tip #3: Keep the Room Cool
While there is no definitive research suggesting that a specific room temperature will prevent your baby from overheating, keeping the room between 68 and 70 degrees fahrenheit will help your little one sleep more comfortably.
If air conditioning isn’t an option, or if your baby’s room runs on the warmer side, place a large bowl of ice in front of a fan that’s directed toward your little one’s crib.
This will help cool the air in the room!
Wrapping Up
Keeping your little one cool during the summer months isn’t just a matter of comfort–it’s necessary to keep your little one from overheating.
Consider …
- Using a muslin swaddle blanket in the warmer months
- Hanging blackout shades or curtains in your little one’s nursery
- Keeping your little one’s room between 68-70 degrees fahrenheit, and using a fan.
