How To Keep Baby’s Room Cool In Hot Weather?

It can be a real struggle for parents to keep their baby’s room at the ideal temperature during the summer months. There are many factors at play – how can you keep your baby cool at night in summer without having them wake up cold if the temperature drops?

Luckily we have gathered top tips to help you out:

  • Buy a Room Thermometer – if there is one essential item for a baby’s nursery after a cot, let it be your room thermometer. Being able to monitor your baby or toddler’s room temperature will enable you to make informed decisions about how to dress the baby for sleep in all weathers. Bonus Tip: A lot of modern baby monitors have thermometers included, ensure you check this with an alternative thermometer before relying on it as these tend to be at a higher temperature. Remember, heat rises so you want the thermometer as close to level with where baby is sleeping as possible.

  • Keep the blinds and curtains closed and the door open for the babies room during the day. Whilst you may feel like to help baby sleep better in the heat you should have the curtains wide open to let in as much air as possible, sunlight coming into the room will make it warmer. Keep the windows open but the curtains closed to avoid this sunny side-effect, as recommended by the lullaby trust site.

  • Use a fan to circulate air around the room but ensure it is not pointing at the baby. A lot of babies actually enjoy the white noise that a fan emits so you may find that it helps soothe the baby to sleep. Great tip – use a bowl of ice or freeze a large bottle of water and place it in front of the fan, this will make the air circulating cold.

  • Use air conditioning if available, there are many portable air conditioning units you can buy. If using an air conditioning unit, cool the room before you put your baby to sleep. Use it for the duration of their sleep, set the temperature for 16 – 18 degrees and make sure the unit is in a suitable position so it’s not blowing cold air directly at the baby. If the room is cooled to lower temperatures, remember to dress your baby accordingly.

  • Some babies won’t settle in the cot with distractions going on, so if you need to close the door of the baby’s room to get to sleep, wait 5 or 10 minutes after they have dropped off and open it up to let air from the rest of the house flow through.

  • If you are having doors and windows open whilst your baby is asleep, don’t forget to use a doorstop or heavy item so that a wind-induced door slam doesn’t wake up your baby!

  • You can also hang a wet towel over the chair, the evaporating water will cool the air

  • Fill a hot water bottle with ice and place it in their cot if they are over 1 year old.

How To Check If A Baby Is Too Hot Whilst Sleeping?

  • The best way to check your baby isn’t overheating when it’s hot at night is to go in and gently place a hand on their chest and their back. A lot of babies’ backs of their heads will get warm – this is completely normal and common in both children and adults alike! So if you focus on the chest you should get an idea of how hot they are.

What To Do If Baby Is Hot Whilst Sleeping?

  • If you do find that your child is too hot at night, whilst you will want to avoid waking them up if you have finally settled baby to sleep, it’s worth working to make the room cooler. If you want to introduce a fan that is particularly noisy, we would recommend starting the fan off in a different room a bit further away but pointing in the direction of the baby’s room and then after 5 minutes bringing it closer whilst ensuring it isn’t pointing at the baby. This will gradually introduce the fan-noise to them without starting them. If you place a frozen water bottle or bowl of ice in front of the fan it will keep the circulating air cooler.

  • Try to keep them on their back, whilst this is a normal safety issue a lot of parents find that when older their baby likes to sleep on their stomach. This is still okay to do but ensure that their cot sheet is tight-fitting and will not go over their face. Similarly, try to avoid using blankets that may end up covering their face. If your child requires a blanket and won’t use a gro bag or sleep without covering, then ensure it is a cellular blanket as these have breathable holes in them.

  • Whilst you will be keeping your baby’s blinds closed (but window open in the heat) you may feel this doesn’t allow for much of a draft. Try propping open the doors in multiple rooms with the windows open in order to create a cooler house overall and a gentle draft of fresh air.

How To Settle Baby To Sleep In Heat?

You will likely find that the heat will either wipe your baby out so they sleep easier, or make them hot and bothered so they take longer to fall asleep. Check out these 3 tips:

  • Return to baby every 20 minutes if they are struggling to sleep in order to offer them a drink of cold water if they are weaned. Try not to engage in conversation during this time for the risk of waking them. If your baby isn’t weaned then try to have a bottle (or breast) handy to top them up with fluid every half an hour.

  • Give baby a cooler bath close to bedtime, this will help to lower their body temperature before bed.

  • Try not to have a baby in an overly cold room for their bedtime routine. If they have been downstairs in a room with a cooling fan, in just a nappy then when they go to bed they are going to feel warmer instantly! 

  • Whilst it may feel uncomfortable and warm for you, try not to be sleeveless if holding them for a feed before bed. Having the skin on skin on the back of the neck when it is hot outside is just going to contribute to them feeling sweaty and clammy. 

  • Try to be patient! It can be frustrating when your baby won’t go to sleep, but it is natural for it to be a more difficult sleep process when the weather is warmer.

What Else Can I Do To Help My Baby In The Summer?

Aside from sleep, the day to day challenges of having a baby or toddler in the summer months can be quite daunting. If you want to read about the best ways to help baby when travelling check out our blog for helping baby to sleep whilst travelling here.

Otherwise, remember these important tips:

  • Don’t leave your little one anywhere it can get hot fast. This includes; the car, covered in a pram, or just sat out in the sun. Covering prams with a muslin will heat them up like a greenhouse. Cover them with safety checked cooling pram covers made for purpose if you have to. Use pram parasols.

  • Sunhats are your baby’s best friend! What can you do if your baby or toddler won’t wear a hat? Keep them in the shade! It’s an unfortunate consequence when we want to enjoy the sun ourselves, but keeping their heads out of the sun is very important. There are several reasonably priced parasols available on the market if your toddler refuses to wear a sunhat.

  • Keep them hydrated! If you are breastfeeding, your milk will naturally adjust to the hot temperature and provide more hydrating milk for your little one, so there is no need to top them up with water if they are under 6 months. Just make sure to offer breast more often. If your baby is on formula, you can offer them sips of cooled boiled water (under 6 months). If your little one is older and isn’t drinking enough water, whilst you may be resistant to offering them a flavoured substitute, very lightly diluted cordial or fresh juice watered down a lot may be necessary if they aren’t drinking. Alternatively, you can make a smoothie using fresh or frozen fruit and even turn that smoothie into ice lollies by freezing it in a suitable container.

  • Paddling pools (in the shade or with hats) are a great way to have fun whilst maintaining a good temperature.
