LifestyleParentingParents have been sharing their concerns about the temperature of their baby's room during the UK heatwave - and it has sparked a conversation about safe sleeping12:24, 26 May 2026Updated 12:24, 26 May 2026With temperatures set to hit highs of 35 degrees in parts of the UK today - making it the hottest day since 2020 - parents are being urged to take extra care to keep babies cool and safe during the heatwave. The Lullaby Trust has issued new guidance as many families struggle to cope with increasingly intense summer temperatures, warning that overheating can increase the risk of sudden infant death syndrome (SIDS).‌Experts say the ideal temperature for a baby’s room should remain between 16 and 20 degrees, but with record-breaking heat making that difficult to maintain, parents are being encouraged to take simple but important precautions. Among the key recommendations is keeping rooms as cool as possible during the day by closing blinds or curtains to block out direct sunlight and prevent heat building up in sleeping areas.‌Parents are also advised to use a fan to circulate air around the room, but it should always be placed safely out of reach and never pointed directly at the baby. Reducing layers is another crucial step. In hot weather, babies may only need a nappy with no additional bedding, helping to avoid unnecessary heat retention while they sleep.‌Parents are also being reminded to monitor room temperature closely using a thermometer, especially during peak heat hours when indoor temperatures can rise rapidly.A key warning sign to look out for is a baby’s skin temperature. If their chest or the back of their neck feels hot or clammy, this may indicate overheating and action should be taken immediately.‌The advice comes as The Lullaby Trust urges parents to stay vigilant both indoors and outdoors during what experts are calling the hottest day since 2020.The charity also highlighted the importance of keeping babies cool when out and about. Parents are advised to stay out of direct sunlight where possible and ensure prams are shaded using clip-on sunshades that still allow air to circulate.Crucially, experts warn against covering prams with blankets or cloths, as this can trap heat and restrict airflow - significantly increasing the risk of overheating.‌Parents are also encouraged to avoid unnecessary travel during peak heat, particularly on public transport, and instead seek out cooler environments such as air-conditioned shops or cafés when possible.Jenny Ward, chief executive of The Lullaby Trust, said the charity has received a surge of concerns from worried parents.She said: “We appreciate how hard it can be to keep babies cool in such hot weather. We would recommend parents regularly monitor their baby’s temperature. If their baby’s skin is hot or sweaty, remove one or more layers and consider moving them somewhere cooler.”Article continues belowAs the UK faces another spell of extreme heat, experts say small changes at home and when travelling can make a significant difference in keeping babies safe and comfortable.Speaking about the issues they've faced during UK heatwaves, one parent said: "I’m letting baby sleep in just a sleep suit.
