How to Keep Baby Cool at Night During the Summer

It’s very important to keep baby cool during the summer nights. Learning how to maintain the right temperature for a baby is something that many parents struggle with at the beginning. Generally, we are told to dress baby in one additional layer that you are wearing yourself. But it’s still possible to overdo it, especially in warmer temperatures, which puts babies at risk for overheating – a known risk factor of SIDS. Being too warm at night can also disrupt your baby’s sleep, so what do you do during those hot summer nights? Here are some tips for helping to keep baby cool and feeling comfortable for a better sleep.

Use a breathable crib mattress

The type of crib mattress you put a baby to sleep on makes a world of difference to how well the baby will sleep. A breathe-through crib mattress allows for ventilation to keep baby cool at night and during naps. The SafeSleep Breathe-Through Crib Mattress by Secure Beginnings features a patented airflow design that lessens the risk of overheating.

Use a summer swaddle

Some swaddles are made of a thicker, warmer material that is best used during colder months. You don’t want to use this same type of swaddle during the summer because it will be too warm for your baby. A light and breathable baby swaddle like the Summer Woombie is ideal because it is made of 100% organic cotton and vented for ultra-breathability.

Adjust the room temperature

Before putting a baby to sleep, make sure the nursery is at a comfortable temperature. The recommended temperature is 65 to 68 degrees Fahrenheit, but all babies are different so check on your baby to make sure he/she is comfortable. You can use an air conditioner or a fan to keep the room feeling cool, but make sure the air is not blowing directly towards the baby.

Check on baby

If you think your baby may be too warm, check for signs like crying, being fussy, or heat rash. Place your hand behind baby’s neck – if it feels warm or damp, you should remove a layer of clothing or adjust the room temperature.

Don’t give baby water

Your instinct when you see your baby sweating may be to offer water, but babies younger than six months should never drink water. Instead, give them more breastmilk or formula to keep them hydrated. In warm weather, you may find baby wants to feed more often to quench his thirst.

Keep curtains closed

It can be tempting to open the curtains during the day to let the sunlight in, but that will also make the room warmer. It’s best to leave the curtains closed to keep it cool and dark. If the light is still coming into the room, you might want to consider getting blackout curtains which will block light, absorb noise, and insulate against heat.

Give baby a bath

Make bath time part of baby’s sleep routine and keep the water slightly cool (not cold) during hot days. This will cool down baby so he will be able to sleep comfortably afterward.

  5. Thank you for the ideas. We have a mini crib mattress. I never thought about a thinner cooler swaddle.

  6. All very good type for a 1st time mom lime me. I have my fingers crossed that I win the gift card as well.

  8. Important to remember if you are hot so is your baby! They really don’t need to be bundled in the summer

  9. I’m so jealous that my sister has one of your mattresses!! I will be moving my baby out of his halo bassinet soon & would love to put him on a secure beginnings mattress!!

  10. Very Helpful! This will be our first summer with our little one so these will come in handy! Thank you.

  11. We sleep at 76 degrees. I told my husband about this blog and we are trying out 70 degrees tonight! Baby boy arrives in 2 weeks or less! Definitely want to prevent SIDS

  12. Thanks for all the info! We didn’t have a mattress like this with our son, but we definitely followed all the other suggestions! :) thanks again! You make a wonderful product!

  13. This is an awesome article. I have to say, my daughter has been sleeping through the night since she was 5 weeks because of this amazing mattress.

  14. I’m a new mom and my husband is in the military so he’s often gone, sleeping has been hard because I’m so afraid if SIDS and in general she doesn’t sleep well, a new mom friend just told me how much she loves her mattress, I’m hoping to give this a try soon, God knows mama could use a good night sleep

    Would love to get a mattress for my toddler and our new little one who is in her way in 2 months.
    Thank you for all
    You do!!

  19. Just got our new mattress all set up, and can’t wait for baby boy to try it once he arrives!

  20. This is the only mattress that I trust my baby on. She was able to roll onto her stomach at 2 days old and has continued to be a tummy sleeper ever since. It was terrifying for me as a first time mom. I was not able to sleep because I lived in fear that my baby would suffocate. My life changed after we got our SafeSleep mattress. I can sleep now knowing that if and when my baby rolls into her tummy she will be able to breath. I tell everyone I know about this mattress. Everyone should have one.

  21. Omg this would be such a relief specially since my baby will born during summer!!! Definitely good tips too!!

  22. Would love to have for my babies when they come. Breathable mattress cause I know my baby will be a sweater in their sleep no matter the season.

  23. My babies always seem to be born during the warmest time of the year. Thanks for sharing these!

  24. We love our secure beginnings mattress! My little one sleeps with her face down and her knees tucked under so this mattress helps ease my mind. We really need a second surface! It’s so time consuming to wash one and wait to be able to put it back on. Especially since my little one still spots up often.

  25. Great info for a first time mom on how to keep baby cool during the summer! 16 days until she is due!

  26. Absolutely love the idea of this mattress and all the awesome tips in the blog post.

  27. these tips are very helpful as my baby is due in 3 weeks, June 1st. so she will be here during the hottest months of the year. The vented mattress is a great idea and the summer swaddle. we will have to make sure we snag those.

  28. A great invention! I shared this with my husband over a year ago when we were TTC and we decided we wanted this for our kids. Happy to announce we are 4 months pregnant with our baby girl. I’m excited to get one!

  29. Expecting in Oct. and I found this blog very helpful! I esp like the tip that recommends dressing the baby in one extra layer compared to what u are wearing.

  37. I foster NAS infants. Due to their drug exposure, they have difficulty regulating their body temperature and are more prone to SIDS. I have heard amazing things about these sleep surfaces and I believe they would be great for my babies!

  38. This would be something really great to try, were expecting our 4th child and I’m always looking for new and innovative baby products.

  39. Good to know, I always thought 65- 68 degrees is a bit on the cold side for a baby, since they can’t really have a warm blanket when they’re small, only swaddles or the like.

  40. After having two miscarriages we finally had our rainbow baby at 35 weeks. This matress gives me such a sense of calmness and peace of mind. Im actually able to sleep without having extreme anxiety! I wish this was around 10 years ago when my older son was a baby.

  73. In San Antonio TX, the summer nights are hot, thank you for sharing the recommended temperature for the nursery, I wouldn’t have guessed it.

  74. I have always been a big believer in bath time before bedtime, it works every time. I’ve also worked in a hospital with many geriatric patients, and it works with them too! :-)
