managing baby and toddler sleep in the heat of summer
Summer is a wonderful season, filled with long days, outdoor adventures, and sunshine. But for parents of babies and toddlers, the heat can sometimes make sleep more challenging. From difficulty settling to frequent night wakings, warmer temperatures can impact both daytime naps and overnight sleep.
The good news? With some simple adjustments, you can help your little one sleep comfortably — and ensure everyone in the family gets a better night’s rest.
Why Heat Affects Sleep
Babies and toddlers are more sensitive to temperature than adults. Overheating can make it harder for them to settle, stay asleep, or reach those deeper stages of sleep that support growth and development.
Some signs that your baby or toddler might be too warm include:
Flushed or sweaty skin
Restlessness during naps or overnight
Rapid breathing or waking more often than usual
Fussiness during settling
Even a small difference in room temperature can impact how well your child sleeps, so creating a cool, calm environment is key.
Tips for Daytime Naps in Hot Weather
Keep the room cool
Use fans or air conditioning if possible (but never direct airflow onto your baby).
Close curtains or blinds during the hottest part of the day to prevent the room from overheating.
Light clothing
Dress your baby in breathable, lightweight fabrics such as cotton.
Avoid over-bundling; sometimes a simple onesie is enough.
Consider nap timing
Try to schedule naps earlier in the day before the hottest part of the afternoon.
Shorter, cooler naps can sometimes be better than struggling through longer naps in a hot room.
Overnight Sleep Strategies for Hot Nights
Cool the room before bedtime
Turn on a fan, air conditioner, or open a window to create a comfortable, breathable environment.
Aim for a sleep room temperature around 18–22°C (64–72°F).
Light bedding and sleepwear
Use a thin sleep sack or light blanket; avoid heavy quilts or layers.
Cotton is your friend — it’s breathable and soft on sensitive skin.
Adjust bedtime routine
Keep wind-down routines calm and shorter if the heat is making your baby restless.
A quick bath or gentle wipe down with a damp cloth can help lower body temperature before sleep.
Positioning and airflow
Ensure your baby’s crib is not near direct sunlight or heaters.
A small, safe fan in the room can help circulate air (never point directly at the baby).
Summer Sleep Safety Tips
Never let your baby overheat — signs include sweating, flushed cheeks, rapid breathing, or vomiting.
Avoid heavy blankets or placing hats and mittens on babies while sleeping.
Hydration matters — babies under 6 months get enough fluids from breastmilk or formula, but older babies and toddlers may need small sips of water during the day.
Monitor the room temperature with a thermometer to make sure it’s in a comfortable range.
The Bottom Line
Summer heat can make sleep tricky for babies and toddlers, but with small, practical adjustments, you can help your child settle, stay asleep, and wake less often. Focus on:
A cool, comfortable room
Light clothing and bedding
Adjusted nap timing and bedtime routines
Remember: even small changes can make a big difference — and calmer sleep for your little one often means more restful nights for you too.
If you’re struggling with naps, bedtime, or night wakings this summer, I can help create a personalised plan that works for your family.
