There’s a simple solution to help babies sleep when temperatures soar. Babies find it hard to sleep during hot weather, so weather you’re away from home on a hot holiday or in the UK which has been experiencing heatwaves and record temperatures so far this summer it can make it hard knowing how to dress your baby on hot nights. Leaving them in just a nappy means they could wake later as night temperatures drop and they get cold. Plus, for many babies, the process of getting into their sleeping bag acts as an important sleep cue and can be hugely comforting.

Choosing sleeping bags made from 100% natural fabrics will be the safest choice for reducing the risk of overheating. Natural fabrics are much more breathable and allow for greater temperature control than their synthetic counterparts. 

Unfortunately, the most popular filling for baby sleeping bags is polyester wadding. Polyester impairs the body’s natural ability to regulate temperature and can very quickly cause overheating. All sleeping bags sold with polyester inside will come with a warning about the temperature limits for that specific tog rating. These will typically include just a 2-3 degree window. This means a lot of guess work is involved before putting your baby to bed: you’ll need to estimate what the likely temperature of the room will be that night, which tog bag to choose and how many under layers to dress your baby in too. 

This is why Pure Earth Collection designed the lowest tog sleeping bag on the market, made from 100% plant-based modal fabric. They’re naturally cooling as modal is 50% more absorbent than cotton. At just 0.2 tog, they’re the ideal solution for those super hot evenings. And they fit from 3 months to 3 years, so they’ll last three whole summers! And the best part? Because we’re only happy when our customers are happy, we offer a 30 DAY SLEEP TRIAL MONEY BACK GUARANTEE.

Other tips for safer and better sleep for your babies during hot summer months

  1. On hot days, keep widows and curtains closed to keep bedrooms cool.
  2. Open windows at night to let cool air circulate.
  3. Make sure babies are well hydrated and offered extra water. For older babies, water bottles can be left next to the cot for them to access if they wake thirsty at night.
  4. Use an organic cotton blackout blind (or natural fabric blind) to block out unwanted sunlight during the longer summer days. This will help promote the production of melatonin – the all-important sleepy hormone.
  5. Natural mattresses are also better and helping control body heat than synthetic foam mattresses. We love Naturalmat Baby for these but there are other great brands out there too.
  6. Check on sleeping babies more regularly in hot weather.
  7. Never point a fan directly at a sleeping baby, this can be dangerous as it can cause sudden temperature loss.

Take time to choose your baby’s bedding to ensure what you are buying is right for you and your lifestyle. Don’t be tricked by clever marketing – be careful to read labels as companies often make claims that bags are 100% natural fabrics when actually in the small print you will see that they have polyester inside. 

The Lullaby Trust’s advice for safer sleep:

  1. Always place your baby on their back to sleep
  2. Keep you baby smoke free during pregnancy and after birth
  3. Place you baby to sleep in a separate cot or moses basket in the same room as you for the first 6 months
  4. Breastfeed your baby
  5. Use a firm, flat mattress in good condition

Things to avoid according to The Lullaby Trust:

  1. Never sleep on a sofa or in an armchair with your baby
  2. Don’t sleep in the same bed as your baby if you smoke, drink, take drugs or are extremely tired
  3. Avoid letting your baby get too hot
  4. Don’t cover your baby’s face or head while sleeping or use loose bedding
