Breastfeeding in the Heat: How to Keep Baby Comfortable and Avoid a Summer Supply Slump
Sweaty baby. Sticky skin-to-skin. Exhausted mom. Yep, it’s summer-aka breastfeeding in the heat.
And if you’re nursing through the heat, you already know—feeding in the warmer months hits different. Between your baby’s sweaty little body refusing to stay latched, the extra skin contact, and the questions about whether your supply is taking a hit, it can feel like a whole new nursing season (literally). But here’s the good news: you can absolutely make it through summer nursing without losing your mind—or your milk supply.
Let’s break down what’s really going on, how to keep baby cool and comfy, and what you can do to protect your supply.

How Breastfeeding in the Heat Affects Feeding
Just like us, babies don’t love eating when they’re hot. Think about it: when you’re sticky and sweaty, a full hot meal probably doesn’t sound amazing. The same goes for your little one.
In the heat, you might notice:
Shorter Feeding Sessions
Babies may pop off quickly or seem less interested in nursing, especially during the hottest parts of the day. That doesn’t necessarily mean something’s wrong—it might just be their way of regulating their own body temperature and comfort.
More Frequent Nursing
Because those feeds are shorter, your baby may want to nurse more often throughout the day. This is totally normal—and actually helpful. Small, frequent feeds help keep them hydrated and make it easier for their little body to manage digestion in the heat.
Fussiness at the Breast
A hot, clingy baby might resist latching, pull away mid-feed, or act generally annoyed at the whole situation. (You’re not alone if you’ve asked, “Why won’t my baby nurse in the heat?!”) This can be especially common during growth spurts or cluster feeding days when they’re already nursing more often.
Worries About Supply
It’s also normal to wonder if your milk supply is taking a hit. You might notice fewer wet diapers, a softer feeling in your breasts, or just a general concern that “nothing’s coming out.” Most of the time, this is tied to your hydration levels or baby not feeding as efficiently—not a sudden supply crash. Keeping yourself well-fed, well-watered, and nursing frequently is key.

Tips to Keep Baby Comfortable While Breastfeeding In The Heat
If your baby’s acting like the breast is the last place they want to be, try these tips to make nursing sessions a little more tolerable for both of you:
Use a Portable Fan
A small, clip-on fan can make a huge difference during nursing sessions—especially if you’re outside. Keep the air moving to prevent overheating.
Try a Cool Cloth
Keep a damp, cool washcloth nearby and gently lay it on baby’s neck or back during feeds. Just enough to help regulate body temp without startling them.
Stick to Shaded Spots
If you’re nursing outside, find shade. An umbrella, stroller canopy, or covered patio can help you both avoid direct sun while still enjoying fresh air.
Dress Baby (and Yourself) Lightly
Skip thick onesies or layers. A lightweight muslin onesie or just a diaper may be all baby needs during feeds. And for you? A breathable, nursing-friendly tank makes a huge difference.
Try a Nursing Pillow Barrier
Placing a breathable cotton blanket or nursing pillow between you and baby can reduce skin-to-skin sweatiness while still keeping baby close. Some babies nurse better when they’re not feeling sticky on your chest.
How to Protect Your Milk Supply in the Summer While Breastfeeding In The Heat
Yes, heat can sometimes mess with your milk supply—but not in the way most people think. You’re not producing less because it’s hot outside; you’re more likely to dip because you’re not getting enough fluids or your baby is feeding less efficiently.
Here’s how to stay ahead of it:
Hydrate (More Than You Think)
Breastfeeding already requires extra water intake to support your body’s milk production. Add summer heat to the mix, and you’re losing even more fluids through sweat—whether you notice it or not. Staying on top of hydration is one of the simplest but most important things you can do to protect your supply and your energy. Aim to sip constantly throughout the day—not just during feeds—and keep a water bottle nearby at all times so it’s easy to stay on track.

Replenish Electrolytes
Sweat isn’t just water—it’s electrolytes. And your body needs those to function. Add an electrolyte drink like this mom-safe option once or twice a day.
Feed Often
Even if baby seems less hungry, offer the breast frequently. Short, frequent feeds are still effective and help protect your supply.
Use Strategic Positioning
If baby’s fighting you because they’re hot, try laid-back or side-lying positions to reduce heat transfer. Nursing in front of a fan can also help some babies relax and feed more effectively.
Still Struggling With Breastfeeding in the Heat?
If your baby is popping off constantly or flat-out refusing the breast, it may not just be the weather. Some babies develop latch issues during stressful seasons (yes, heat counts), growth spurts, or after a period of bottle preference.
You don’t have to figure it out alone. If nursing feels harder than it should:
Grab The Latch Lookbook for troubleshooting latch issues and getting back to basics.
Or book a consult with me for one-on-one support.
Hot weather nursing isn’t always easy, but with a few smart shifts, you can make it work—for you and your baby. Your body knows what it’s doing, and when you give it what it needs, you’ll both stay nourished, hydrated, and ready to beat the heat.
