Breastfeeding in a Heatwave
A Gentle Guide to Keeping Baby (and You) Cool, Hydrated, and Comfortable
When the temperature soars, everything feels a little more intense — especially when you’re feeding a baby. Whether you’re at home, outdoors, or cluster feeding through sweaty nights, breastfeeding in a heatwave can be challenging.
You might be wondering:
Does baby need extra water?
How can I stop us both from overheating?
Is it normal for feeding patterns to change?
At Neutral Nest, we’re here with calm, practical tips to help you navigate hot weather feeding — with softness, confidence, and lots of cold water nearby.
Do Breastfed Babies Need Water in Hot Weather?
No — exclusively breastfed babies under 6 months don’t need extra water, even in a heatwave.
Your breast milk adapts beautifully to your baby’s needs. In hot weather, it becomes naturally more watery and hydrating — like their own built-in electrolyte drink.
For older babies (6 months and up) who are eating solids, a little cooled, boiled water can be offered between feeds — but milk should still be their main source of hydration.
Signs Your Baby Is Getting Enough Fluids
Even in hot weather, your baby is likely doing just fine if:
They’re feeding regularly (which may mean more often than usual)
They have at least six wet nappies in 24 hours
Their wee is pale or clear
They’re alert, settled, and responsive
Their lips and mouth are moist
If you’re ever unsure — especially if your baby seems sleepy, listless, or has fewer wet nappies — contact your GP or health visitor for advice.
How to Stay Cool While Breastfeeding
Here are some small adjustments that can make a big difference during a heatwave:
Dress Lightly
Choose breathable, natural fabrics like cotton or bamboo for both you and baby. A nappy and a light muslin top or vest is often plenty for baby indoors.
Skin-to-Skin, the Cooler Way
Skin-to-skin can still be calming — but it gets hot quickly. Try placing a thin muslin cloth between your bodies to reduce stickiness and sweat.
Keep Fluids Flowing
You need hydration too. Keep a large water bottle nearby and sip regularly, especially during or after feeds. Coconut water, herbal teas, and juicy fruits also help.
Create a Cool Feeding Spot
Feed in the coolest room of the house, or near a fan (aimed away from baby). Blackout blinds, cooling curtains, or damp muslins on open windows can help reduce heat build-up.
Feed Little and Often
Your baby may prefer shorter, more frequent feeds. That’s okay — follow their lead. It’s their way of staying hydrated and comfortable.
Night Feeds in Hot Weather
Night feeds can feel especially uncomfortable when it’s warm. Try these ideas:
Use light bedding or sleep on a towel or muslin to absorb sweat
Keep a cool flannel or spray bottle nearby for quick refreshment
Consider a lukewarm shower before bed to lower your body temperature
Keep lighting low to reduce both heat and stimulation
Breastfeeding Out and About in the Heat
Plan feeds around the cooler parts of the day when possible
Feed in shaded spots or use a light, breathable muslin for coverage if needed
Avoid feeding in direct sunlight or in a hot car — always find a cooler space
Bring plenty of water, a hand fan, and a wide-brimmed hat for you both
Final Thoughts
Your body is working hard to nourish and nurture your baby — especially in hot weather. You’re doing an incredible job.
If feeds feel more frequent, or everyone feels a little more irritable, you’re not doing anything wrong — it’s just the heat. Go gently, take breaks, stay hydrated, and don’t hesitate to reach out if you need support.
At Neutral Nest, we’re here for the real, often sweaty, side of early parenthood — with practical essentials, emotional care, and reminders that you’ve got this, even on the warmest days.
