When temperatures rise, many parents find themselves checking on their baby more often than usual. It's completely natural to worry about whether your little one is too hot, too cold, or sleeping comfortably.

Here are some of the most common questions parents ask about keeping their baby cool at night, along with practical tips to help your baby sleep safely during warm weather.

How Hot Is Too Hot for a Baby's Room?

The ideal room temperature for a sleeping baby is between 16°C and 20°C.

Don't panic if your baby's room occasionally goes above this during a heatwave. Instead, focus on keeping the room as cool as possible by:

• Closing curtains and blinds during the day
• Keeping windows shut while the sun is directly on them
• Opening windows in the evening when temperatures begin to fall
• Using a fan to circulate air (but never blowing directly onto your baby)

If your baby's room feels warm, adjust their clothing accordingly and keep an eye on how comfortable they seem.

Can a Baby Sleep in Just a Nappy?

Yes, in very warm weather many babies are perfectly comfortable sleeping in just a nappy.

Some babies may prefer:

• A nappy only
• A nappy and short-sleeved vest
• A lightweight bodysuit

The key is to avoid overdressing. Babies are more likely to become uncomfortable from being too hot than from having too few layers during a warm summer night.

What Should a Baby Wear to Bed in a Heatwave?

What your baby wears depends on the room temperature.

During very hot nights, less is usually best.

Choose:

• Lightweight, breathable fabrics such as cotton
• Loose-fitting clothing
• The lowest tog sleeping bag recommended for the temperature, if using one

Avoid:

• Thick sleep suits
• Heavy blankets
• Quilts or duvets
• Multiple layers

Remember that babies don't need extra layers just because they're babies.

Should I Use a Fan in My Baby's Room?

A fan can help improve air circulation and make a room feel cooler.

However, it's important to use it safely.

You should:

• Position the fan away from the cot
• Ensure it is not blowing directly onto your baby
• Keep cords well out of reach
• Use it to move air around the room rather than create a cold draft

Some parents find that placing a bowl of cool water elsewhere in the room can help make the air feel slightly fresher.

Can I Give My Baby a Cool Bath Before Bed?

Yes. A lukewarm bath before bedtime can help your baby cool down and settle for sleep.

The water should feel comfortably warm rather than cold.

Avoid:

• Ice-cold baths
• Cold showers
• Sudden temperature changes

Many babies find a gentle evening bath both cooling and calming.

Can I Cool My Baby's Feet With Water?

A gentle splash in tepid water can help your baby feel more comfortable on a hot day.

Some parents allow their baby to paddle their feet in a shallow bowl of tepid water while closely supervised.

You can also use a soft cloth dampened with tepid water to wipe your baby's feet, legs, hands or arms.

Avoid using very cold water or ice packs, as these can be uncomfortable and may cause the body to react by trying to conserve heat.

How Do I Know If My Baby Is Overheating?

Many parents check their baby's hands and feet, but these are not always reliable indicators of body temperature.

Instead, feel:

• Your baby's chest
• Their back
• The back of their neck

Signs that your baby may be too hot include:

• Sweating
• Flushed cheeks
• Damp hair
• Fast breathing
• Restlessness
• Feeling hot on the chest or back

If your baby seems too warm, remove a layer of clothing and continue monitoring them.

Can Hot Weather Make Babies Wake More Often at Night?

Yes.

Just like adults, babies can struggle to sleep when they are too warm.

You may notice:

• More frequent waking
• Increased fussiness
• Difficulty settling
• More night feeds

This is often temporary and usually improves once temperatures return to normal.

Should I Give My Baby Extra Feeds in Hot Weather?

Babies can become thirstier during hot weather.

Breastfed babies often naturally feed more frequently when temperatures rise.

Formula-fed babies may also want feeds a little more often.

A good sign that your baby is well hydrated is that they continue to produce plenty of wet nappies throughout the day.

If you are concerned about hydration, always seek advice from your health visitor or healthcare professional.

Should Bottles Be Kept Cool During Hot Weather?

Prepared formula should always be stored and used according to current feeding guidelines.

Many parents find that keeping feeding equipment cool and hygienically stored helps during warmer weather.

Always follow current safe preparation and storage recommendations for infant milk.

Final Thoughts

Summer nights can be challenging for parents and babies alike, but a few simple adjustments can make a big difference.

Keep the room as cool as possible, dress your baby appropriately for the temperature, avoid heavy bedding, and check your baby's chest or neck rather than their hands and feet.

Most importantly, remember that it's normal to check on your baby a little more often during a heatwave. You're not being overprotective — you're being a parent.

And if you're comfortable, chances are your baby will be too.
