Baby Pajamas for Summer: How to Keep Your Little One Cool and Comfortable

When the temperature rises, dressing your baby for sleep can get a little tricky. You want to keep them cool and cozy without sacrificing comfort or safety. So, what’s the best type of baby pajamas for summer?

In this article, we’ll break down the best summer sleepwear for babies, whether you’re shopping for your own little one or stocking up on wholesale infant clothes for resale.

What Should Babies Wear to Sleep in Summer?

During the warmer months, breathable fabrics and lightweight designs are key. The goal is to keep your baby from overheating while still making sure they feel secure and snug. Here are the best summer-friendly baby pajama options:

  • Short-sleeve bodysuits or rompers – Perfect for warmer nights, especially when made from 100% cotton. These pieces offer comfort, mobility, and easy diaper access.
  • Sleeveless or short-sleeved sleep sacks – Ideal for newborns and younger babies who still need that cocooned feeling but without the extra layers.
  • Footless pajamas – Great for allowing a bit more airflow, especially for babies who tend to get warm while sleeping.
  • Onesies or even just a diaper – On especially hot nights or in homes without air conditioning, some parents opt to dress their baby in just a diaper with a lightweight muslin swaddle or blanket nearby.

Do Babies Need Footie Pajamas in Summer?

Footie pajamas aren’t always necessary in the summer, especially if your home stays warm overnight. However, if your baby is used to wearing them and your home is kept cool with air conditioning, a lightweight, breathable footie pajama made from natural fabrics like cotton or bamboo can still be a good option.

The key is to monitor your baby’s comfort. A quick check on the back of their neck can tell you whether they’re too warm. If they feel sweaty or clammy, it’s time to swap to lighter baby clothes.

Summer Pajama Fabric Tips

When selecting baby pajamas for summer, look for:

  • 100% cotton or bamboo – Both fabrics are soft, breathable, and gentle on sensitive skin.
  • Moisture-wicking properties – Helps keep baby dry and comfy.
  • Tagless designs and soft seams – Especially important for overnight wear.

Avoid synthetic materials like polyester in hot weather, as they can trap heat and irritate the skin.

If you’re in the business of decorating or reselling children’s clothing, summer is a perfect time to offer breathable, high-quality basics. Lightweight infant sleepers, newborn pajamas, and soft rompers make great canvases for screen printing, embroidery, or heat transfers.
