Baby Sun Protection Essentials
Baby Safe Sunscreen (for 6 months+)
For babies over 6 months, pediatricians recommend mineral-based sunscreen.
Look for:
SPF 30-50
Broad spectrum protection
Fragrance-free formula
Water-resistant
Top Pick: Mineral SPF 50 Baby Sunscreen (Tubby Todd is a trusted brand and great for sensitive skin). This set comes with two baby-safe sunscreen sticks too — easy to keep in your diaper bag or car.
Pro mom tip: use a makeup sponge to apply sunscreen on your baby’s face as that seems to agitate them less than using your hands.
Baby Sun Hat
Since babies can’t wear sunscreen until they are 6 months it’s super important to keep their heads and bodies covered in light breathable fabrics. A wide-brim hat with a chin strap is one of the best warm weather baby essentials. I like to keep a sun hat in my diaper bag during the summer months so I always have it accessible.
Best for everyday outings: Floppy Hat Style/Bucket Hat Style
This is one of those items you’ll use weekly, if not daily, on walks, park trips, and stroller outings.
If you’re planning a longer trip or flying with your baby, I put together a full guide on how to prepare, what to pack, and how to make flying with a baby easier.
How to Keep Baby Cool in Hot Weather
Overheating is the biggest risk in summer. Babies sweat less and can get heat exhaustion quickly.
Here’s what actually helps.
Clip-On Stroller Fan
Stroller fans are especially helpful in the summer when you’re dining outdoors or taking long walks. I recommend having two fans - one to keep in the stroller at all times and then one to keep in your car, that way you always have one you can attach to the car seat or wherever in case you are out in the warm weather without your stroller.
Look for:
Flexible tripod legs for easy hook on to the stroller or car seat
Rechargeable battery
Adjustable speeds
Best stroller fan for baby: This stroller fan has so many fun colors to choose from!
Water Mist Fan
This water mist fan is perfect to throw in the diaper bag when you know you’ll be outside in the heat for a while like at the zoo or a carnival.
Breathable Summer Clothing
If you’re wondering how to dress baby in 90 degree weather, here are some practical tips.
Choose:
100% cotton
Bamboo blends
Lightweight rompers
Minimal layers
The best lightweight options are typically cotton or muslin rompers and breathable cotton short-sleeve bodysuits.
Portable Shade Solutions (Like a Pop-Up Outdoor Tent for Baby)
We want to avoid direct sun exposure for babies so having a portable pop-up tent or pack and play can be super helpful. I also think it’s worth investing in one of these because
It gives you a soft place to lay baby outdoors and blocks the outdoor elements from baby
A baby shade tent gives you a safe place to lay baby to keep them away from pets and your toddlers, if you have other older children, especially if they are kicking soccer balls around or doing other outdoor activities.
Baby Shade Tents
We have The California Beach Co. Pop 'N Go® Playpen and I’m so glad I invested in one of these.
I love it because it has grown with my babies - even my four and two year old have a blast playing in it. It also can serve multiple purposes - we use it in our backyard but it’s also our go-to for beach trips and park outings too. It comes with a UV-protective, UPF 50 shade cover to block the sun, it’s fast to put up, and compact for travel.

Another option I like for newborns to 4 months is a portable bassinet and baby dome. This is smaller when set up so if you have a small outdoor space this would be a good option for a young baby. Since it is smaller in general. it can also be used inside too if you want to protect baby a bit more from indoor pets or toddlers.
Beach & Pool Must-Haves for Baby
If you're planning lake days or a beach trip with baby, these are the real essentials.
UPF 50+ Sun Protection Swimwear
Again, make sure baby’s skin is protected from that sun!
UPF sun protection swim for baby: Girl swim/Boy swim
Swim Diapers (Reusable or Disposable)
I’m a disposable swim diaper kind of girl but some moms choose reusable swim diapers for a more eco-friendly and cost-effective option.
Baby Water Float
We have the Mambobaby float(lots of colors and patterns to choose from) and I could not recommend enough. It gives me so much peace of mind in the water with a baby because baby is strapped in security and the device is structure in a way that prevents tipping.
Wet Bags + Beach Bag Waterproof Zipper Pouches
Wet bags are perfect for wet swimwear, dirty clothes and diapers after use.
I also use mesh zipper pouches in our Simple Modern beach bag to keep things organized and waterproof — one for snacks, one for diapers and wipes, one for clean clothes.
Travel Essentials for Hot Weather
Getting out of the house with a baby in the summer can feel like a lot, but having the right essentials makes it so much easier.
Whether you’re running errands, heading out for the day or traveling, these are the items I found made the biggest difference in keeping my baby comfortable (and honestly, making everything feel less stressful).
Car rides can get hot quickly, especially in the summer. These are a few simple things that help keep your baby more comfortable while you’re on the go
Simple Modern Beach Bag (Bogg Bag Dupe)
This is THE mom bag to hold it all. These waterproof rubber tote bags (this is the Simple Modern brand, similar to the Bogg bag but way more affordable!) have become a favorite for a reason. They fit a lot and are super easy to clean - just rinse them out! Perfect for sandy beach days, trips to the park, etc.
I got the extra-large size and it fits several beach towels, my daughters’ two swim vests, sunscreen, extra diapers and wipes, and snacks. You may even consider the large size if you’re looking for something a little lighter.
Lightweight Travel Stroller or Baby Carrier
A lightweight stroller or baby carrier is one of those non-negotiable beach and travel essentials because what works best really depends on your setup for the day.
We’ve personally used the Summer Infant 3Dlite stroller and loved it for travel. It’s super lightweight, folds easily, and reclines almost flat making it perfect for beach naps, airport days, or long outings where you don’t want to haul a heavy stroller. It’s also budget-friendly, which makes it less stressful if it gets bumped around during travel.
That said, after having multiple kids, I’ve found that our go-to has shifted toward the Zoe lightweight double/triple stroller for trips. It’s become our preferred travel stroller when we need something that can handle two kids at once without feeling bulky. It’s especially helpful for beach boardwalks, airports, and vacation days where one child wants to walk, one wants to ride, and I still need flexibility.
In situations where a stroller just isn’t practical, a lightweight, breathable baby carrier is essential. It keeps your baby close, keeps your hands free, and avoids the frustration of trying to push wheels through sand.
Portable Fan for Baby
Again, make sure you always have a clip-on stroller fan on hand for airflow in the car, stroller, etc.
Baby Muslin Blanket
A lightweight muslin blanket is a must-have for chilly summer nights or to use as a lightweight breathable nursing cover during the summer months.
Feeding and Hydrating Baby On-the-Go
Feeding your baby while you’re out in the heat just takes a little more planning. These are a few things that made it easier for me.
Insulated Portable Breast Milk Chiller
If you’re breastfeeding or pumping and planning to be out of the house for more than a couple hours, this is one of those things that makes a huge difference.
In the beginning, I tried using a regular cooler and ice packs — and it worked, but it was bulky, inconvenient, and honestly just one more thing to manage. Switching to a portable breast milk chiller simplified everything.
The one I recommend (and what I personally would choose again) is the Ceres Chill Breastmilk Chiller.
Here’s why it stands out:
Keeps breast milk cold for up to 20 hours
No need for separate bags or multiple bottles
Designed specifically for pumping moms
Compact enough to throw in your diaper bag
It’s one of those products that gives you a lot more flexibility. You’re not rushing home, stressing about milk storage, or trying to plan your entire day around feeds or pumping sessions.
If you’re planning any kind of travel, long outings, or even just want more freedom day-to-day, this is 100% worth having.
Insulated Sippy Cup (for Babies 6+ months)
Once your baby is 6+ months and starting solids, having cold water on hand while you’re out becomes really helpful. An insulated, spill-proof sippy cup is one of those small things that just makes outings easier. It keeps water cooler for longer and helps you avoid leaks in your diaper bag.
Look for stainless steel, a straw that can flip up and down to keep dirt and germs away, BPA-free, and designed to keep drinks cold while still being easy for little hands to use.

Insulated Snack Pouch
If your baby is eating solids, pack a small insulated pouch with easy on-the-go healthy snacks for babies:
Cut up fruit
Yogurt melts
Teething crackers
Puree pouches
Fruit bars
Puffs
Comfortable and Supportive Nursing Bra
Nothing is worse than a hot and uncomfortable nursing bra in the heat. Make sure you have a supportive nursing bra that is actually comfortable and keeps you cool, so you can skip the fuss and truly enjoy hanging outside with your baby.
I’ve done a complete roundup of the best nursing bras so you can skip the research!
What to Pack in Your Diaper Bag for Summer
Your diaper bag ends up working overtime in warm weather. These are the essentials I always make sure to have with me:
An extra outfit (or two) in lightweight, breathable fabric
Wipes and diapers
A portable changing pad
A sun hat
Travel-size sunscreen (for babies 6+ months)
Water in an insulated sippy cup (for babies 6+ months)
One thing I didn’t expect was how often I’d need a backup outfit. Between sweat, spit-up, and diaper leaks, it adds up quickly in the heat!

Hydration Tips for Babies in Hot Weather
Keeping your little one hydrated in the summer is one of the most common concerns parents have — and for good reason! Babies are more susceptible to heat and can get dehydrated quickly. Here’s what you need to know:
Babies under 6 months: Stick to breastmilk or formula on demand. These provide all the hydration they need.
Babies over 6 months: You can start offering small sips of water, especially when they’re eating solids. Always check with your pediatrician if you’re unsure.
Helpful gear for staying hydrated on the go:
Insulated breast milk chiller to keep breastmilk at the right temperature
Insulated cups (6+ months) to keep water on hand
Signs Your Baby Might Be Overheating
As a parent, it’s so important to recognize the early warning signs of overheating. Keep an eye out for:
Flushed or red skin
Rapid or labored breathing
Unusual sleepiness or fussiness
Fewer wet diapers than usual
Warm chest or back to the touch
If you notice any of these, move your baby to a cooler space immediately, remove extra layers, and offer fluids if they’re old enough.
