Hot days, melty snacks, surprise diaper blowouts… summer with a baby or toddler is a whole vibe. But when your diaper bag is prepped right, you can handle anything from a sticky ice cream meltdown to a sudden nap-on-the-go. 

Here’s your go-to guide for what to pack in your summer diaper bag, so you’re always ready for sunshine, sweat, and everything in between. 

1. The Basics (Still Essential)

No matter the season, these items are your year-round MVPs: 

1. Diapers (1 for every hour out, just in case) 
2. Wipes (lots!) 
3. Diaper cream 
4. Extra outfit (maybe two if you’re going far!) 
5. Snack container or pouch 
6. Sippy cup or bottle 

2. Sun Protection Must-Haves 

1. Baby-safe sunscreen (SPF 30+, mineral-based) 
2. Wide-brimmed hat with chin strap 
3. Sunglasses (toddler version with strap if needed)
4. Light muslin blanket for instant shade or stroller cover
