Having a Summer Baby? Here's What Your Hospital Bag Actually Needs

I had my first baby in July. In Texas. Let me tell you what nobody warned me about.
The hospital was freezing. Like, aggressively air-conditioned. I packed all these light, breezy outfits and ended up shivering in a hospital gown, wrapped in thin blankets, begging my husband to find me a sweater.
But the trip home? Brutal. 98 degrees. Baby in a car seat in direct sunlight. Me, sweating through my postpartum pad, already regretting not starting the car earlier to cool it down.
Summer births are weird. Here's what I learned.
The Hospital Is Cold, But...
Yes, hospitals crank the AC. You'll probably want a light cardigan or sweatshirt. Bring thin socks. Maybe a light blanket from home.
But don't pack like you're going to Antarctica. The hospital is cold, not arctic. A few warm layers are enough.
The real challenge is everything that happens outside the hospital.
What to Pack for Mom
Clothing:
- Short-sleeve nursing tops or pajamas (3-4, you'll sweat)
- A light cardigan or zip-up for the AC
- Loose shorts or lightweight pants
- A comfortable nursing bra (breathable fabric)
- Disposable underwear (honestly the best invention, especially in summer)
- Flip-flops or slides
- Thin socks for the hospital
Because it's hot:
- Extra towels or washcloths
- A handheld fan or one of those USB desk fans
- Facial mist spray (sounds bougie, feels amazing)
- Hair ties (get that hair off your neck)
- Dry shampoo
Going home:
- Loose dress or flowy clothes (fitted anything will be miserable)
- Sunglasses
- A hat if you want
What to Pack for Baby
Less is more. Summer babies don't need layers.
- Short-sleeve onesies (3-4)
- A couple of lightweight rompers
- Thin cotton receiving blankets (not fleece!)
- A hat for sun protection going home
- Thin socks for the hospital AC
- Maybe a belly band/binder to keep their tummy covered in AC
The going-home outfit should be simple and light. A cotton onesie and thin blanket is fine. Don't overdress them just because you think "new babies need to be warm." In summer, they're more likely to overheat.
The AC vs Heat Problem
Here's what nobody tells you: newborns can't regulate their temperature well. In summer, this means:
In the hospital (AC blasting): Baby might need a light layer. Socks. Maybe a hat while sleeping.
Going home (actual summer weather): Baby needs to be cool. Just a onesie is often enough. Light blanket over the car seat is fine, but don't bundle them up.
Feel the back of their neck. If it's warm and dry, they're good. If it's sweaty, they're too hot. Cool hands and feet are normal and not a sign they're cold.
The Car Seat Situation
This is critical. Please read this.
Before you leave: Start your car 10-15 minutes early with the AC on full blast. A hot car seat can actually burn baby's skin. The metal buckles get scorching.
Sun shades: Put them in your windows before you go to the hospital, or have someone do it before they pick you up.
Touch the car seat before you put baby in it. The surface, the straps, the buckles. If it's hot to your hand, it's too hot for baby.
Summer Postpartum Is Different
A few things nobody mentioned:
You will sweat. A lot. Postpartum hormones are wild, and adding summer heat makes it worse. Pack extra underwear. Shower when you can. Change your pads frequently because hot + moisture + healing = potential problems.
Hydration is serious. If you're breastfeeding in summer, you need to drink constantly. Like, way more than you think. Dehydration affects milk supply and your recovery.
AC is your friend. I know some people say new moms shouldn't use air conditioning - that's outdated advice. Use the AC. Keep it around 72-76°F. Just don't point it directly at baby, and wear light long sleeves if you're worried about your joints.
You can shower. Old advice said no showers for weeks. Modern doctors say shower when you feel up to it (usually day 2-3 after vaginal birth, after incision check for C-section). In summer, you'll want to.
Common Summer Baby Questions
Can I take baby outside?
Yes, but be smart about it. Avoid direct sunlight and the hottest parts of the day (10am-4pm). Early morning or evening is better. Always have shade. Babies under 6 months shouldn't wear sunscreen - use shade and clothing instead.
What about mosquitoes?
Keep baby covered with light clothing or a stroller net. Most bug sprays aren't recommended for newborns. Citronella and natural alternatives aren't proven effective. Physical barriers (nets, long sleeves) work best.
Can baby get diaper rash more easily in summer?
Yes. Heat + moisture = rash. Change diapers more frequently. Let baby air out with no diaper sometimes. Use barrier cream. Consider the more breathable diaper brands.
Is it okay if baby seems sweaty?
If they're just a little damp, they might be too warm - remove a layer. If they're sweaty AND fussy AND have a red face, cool them down. Babies can overheat quickly.
What I Wish I'd Known
-
Pre-cool everything. Car, car seat, your house before you get home.
-
Pack less. Summer clothes are small. You don't need much.
-
Bring a layer for the hospital AC but don't overpack warm stuff.
-
Expect to sweat and pack accordingly.
-
Going home is the hard part - plan for the heat, not the hospital.
-
Baby doesn't need to be bundled just because they're new. Feel their neck, not their hands.
Having a summer baby has its perks - you're not shuffling through snow to doctor's appointments, recovery clothes are simpler, and there's plenty of daylight for those early weeks. Just be prepared for the heat.
