Temperature of house for newborn

16 replies

BS222 · 20/06/2025 22:10

Im 37 weeks pregnant with ny first baby, due in the middle of July. I am worried about the temperature of my house and how unsafe it will be for our newborn when sleeping and in general. I know we are having a heatwave at the moment so my house is hotter than usual but only by a few degrees. Mine and my partners bedroom is currently 27 degrees and downstairs is 25 degrees! The curtains have been closed all day and windows have been open for ventilation, the fan is also turned on and rotating on the maximum setting as soon as we’re back from work to try and bring the temperature down but nothing seems to work. We also have the patio doors open downstairs when we’re home to get some more ventilation.

For the past couple of months our bedroom has been no cooler than 21 degrees, even when it’s not hot outside. I know it is ideal for where the baby sleeps to be between 16-20 degrees so I’m worried that we’re unable to create a safe sleep space for our baby when he arrives.

Can anyone please offer an advice on how to cool down our room and make it safer? Thanks in advance 🩵

Thebaby will be fine. They are born into s lot hotter climates than the UK! Dress them lightly, and as odd as it sounds make sure they aren't chilly from being in a draught.

My son was born during the heatwave in 2022 when it hit 40°C. He, and all the other newborns, spent the night in just a nappy on the hospital ward and were closely monitored. Baby will be fine. Dress them very lightly and make sure you check on them a lot during the night if they are still in the sleepy first few days.

If you can afford one the portable Aircon units are great. Added benefit of being bloody noisy so you get white noise thrown in for free.

They will be fine; as said just dress them lightly. I very rarely got the temperature below 20 especially during the first part of the night even in winter. 16/17 degrees is quite chilly. I really stressed about this with my first but it’s not something to get worked up about

Dress lightly, check temperature of baby, use muslins rather than blankets. They have babies in far hotter climates!

Keep the windows closed except for early morning or late at night. Otherwise you're just letting hotter outside air into a cooler house. As soon as the outside air temperature is warmer than inside close windows and blinds.

My room is definitely hotter than 21 degrees, even in winter. My son's 10 months now and hes been fine. Don't swaddle baby, a 0.5tog sleeping bags much safer, just check the label or online for what to dress baby in depending on the temperature. And just check her back/chest to see if she's hot

Snap! Baby due middle of July and our house is 28.5 degrees at night.
My DD (8) was born during a really hot summer and she slept in a nappy on the hottest nights.
We’re hoping to get a portable air-con unit this time but failing that, we have been keeping the curtains closed all day and then once it’s dark, put the fan in front of the window with the curtain open. It drags in the outside air through the fan into the room and it’s so much cooler.

MoserRothOrangeandAlmond · 21/06/2025 09:03

Daughter was born in a heat wave in July 6 years ago and I had the same concerns.
basically for the first week of her life she spent it in a nappy.
Midwife said that babies are born in hotter climates than ours. We basically followed the rule re blinds closed etc and opening windows after the peek xxxx

Phunkychicken · 21/06/2025 09:09

DS was born 20 years ago and I remember wailing to DH that our bedroom was 29 degrees and the guidance said 21 was the max.

I hid the thermometer and just focused on making it feel as cool as possible with blinds/fans etc. Hanging up damp sheets by windows. And got DS a fab thin cotton/towelling 0.5 tog sleeping bag. And v cute vests that were like grown up vests that were cut off at the waist that he'd wear with only a nappy.

Also spent a lot of time in Macdonald's and our local pub with air conditioning.

I honestly wouldn’t recommend one for your baby’s room. They aggressively blow out cold air, you have to have a window open which means it gets light early.

OP, all the stuff about ‘baby must be in a cool room’ isn’t helpful for those of us who have a newborn when it’s hotter than the sun! it just makes you anxious, when there’s nothing you can do and it’s very unlikely to cause a problem! Of course it’s confirmation bias, but so any of us know a baby that was unwell or
died in the heatwave of 2022?

Baby should just be in a nappy, this is what my midwife said. My ‘heatwave baby’ is now nearly 3 and sleeps beautifully in her roasting hot room! We have arguments to stop her using a duvet and wearing long pjs.

I think portable air con units are terrible for bedrooms, but that’s just my opinion.

we got proper air con units fitted and they are great. Our newborn (or not so new anymore!) sleeps in 21 degrees in his usual bag and onsie. My heatwave older baby… sleeps in shorts in 30 degrees (no air con in her room as it’s on the lower floor) and is fine.

SENMum2025 · 21/06/2025 09:22

Get an evaporation cooler? It’s not as energy intensive as an air con. It basically blows air over ice blocks and gently blows it into the room. I’ve not had one but I saw them
recently when researching fans!

I know that babies are born in hotter climates but if you can cool the room down to a comfortable temperature then why wouldn’t you? I lived in 30-35 degree heat and we couldn’t survive without air con. I would have found skin to skin to be really sticky and uncomfortable. I have a very young baby now and it’s easier to keep her in a baby gro than try to pick her up in her bare skin because we’re both so sticky.

Thank you everyone, this has made me feel a lot less worried, I really appreciate the help and advice🩵

My daughter was born at the same time and we had the 40 degree days as one of our first nights at home. Strangely they still put her in a blanket in hospital even though it was hot as hell on the ward. You can have the baby just in a nappy or vest if needed. We also used the Love to Dream 0.2 tog swaddles which are OK up to 27 degrees. Much safer than normal swaddling as you only have one layer of light fabric.

We were checker every 2 hours during the night as we were told to feed every 2 hours for the first week.
