How to Dress a Baby for Sleep

Dressing a baby for sleep can feel like a puzzle, especially with so many factors like temperature, safety, and comfort to consider. Whether you’re a parent, grandparent, or another family member caring for a little one, figuring out the best approach to dress a baby for sleep can be confusing. Should you use multiple layers? What about sleep sacks? And how do you know if your baby is too hot or cold?

In this guide, we’ll walk you through how to dress a baby for sleep using Moms on Call’s tried-and-true methods to ensure your baby stays comfortable and safe. We’ll cover fabric choices, layering techniques for different seasons, and safe sleep practices to help you create a peaceful sleep environment for your little one.

Choosing the Right Fabrics for Baby Sleepwear

Fabric choice is essential when it comes to dressing a baby for sleep. Babies have sensitive skin, and the right fabric can make all the difference in keeping them comfortable throughout the night.

Fabric Importance

The fabric you choose should be soft, breathable, and gentle on a baby’s skin. Babies are much more sensitive to temperature changes, so it is important to select fabrics that help regulate body heat effectively.

Ideal Fabrics

We recommend cotton and bamboo as the best options for baby sleepwear. These natural materials are soft and highly breathable, allowing air to circulate and helping to prevent overheating. Cotton is a classic choice, while bamboo offers a lightweight, silky feel—perfect for keeping your little one cozy without feeling too hot.

What to Avoid

When choosing sleepwear, avoid synthetic fabrics like polyester, which can trap heat and irritate sensitive skin. Always choose easy items to put on and take off, such as those with zippers instead of snaps or buttons. This makes nighttime changes much easier for anyone caring for the baby. Also, choose sleepwear that can either fit over the baby’s head comfortably or open fully for convenience.

Room Temperature

No matter the temperature outside, the room temperature should always be 68-72°F. This is the optimal temperature for restful sleep. Maintaining a consistent temperature will also help take the guesswork out of dressing a baby for sleep.

Layering Techniques for Seasonal Changes

As seasons change, so should your approach to dressing a baby for sleep. Here’s how to keep your baby comfortable in every type of weather.

Dressing for Warm Weather

During warmer months, simplicity is key. Light fabrics and minimal layers are your best friends. A short-sleeved onesie of breathable cotton is usually enough to keep your baby cool and comfortable. Cribs should be bare of anything except a mattress with a fitted sheet. Avoid adding extra blankets or layers. Not only do these pose a suffocation risk, but they could cause overheating. If you’re concerned about cooler nights, add zippered-footed pajamas.

Dressing for Cooler Weather

When temperatures drop, layering becomes important. Start with a soft, short-sleeved cotton onesie as the base layer. Over this, you can add footed pajamas to keep your baby’s entire body warm. For babies under 12 weeks of age and 12 pounds who are not showing signs of rolling over, a swaddle blanket will provide an additional layer of warmth and keep their startle reflex from waking them.

Transitional Seasons

Weather can be unpredictable in transitional seasons like spring and fall. The key here is to monitor the room temperature (ideally between 68-72°F) and adjust layers accordingly. Use a base layer of a short—or long-sleeved onesie, and add light, zippered-footed pajamas if needed. Don’t overthink it—the best approach is to adjust based on the baby’s comfort and room temperature.

Safe Sleep Practices and Sleepwear

Ensuring a safe sleep environment goes beyond just dressing the baby for sleep. It’s about creating conditions that promote restful, safe sleep every night.

Swaddling for Newborns

Swaddling is a wonderful way to help newborns feel calm and secure. When done correctly, it mimics the feeling of being held, reducing the startle reflex and helping babies settle into a deeper sleep. However, it’s essential to swaddle safely—always keeping the swaddle snug around the baby’s torso but loose around the hips and legs. Swaddling is safe for babies under 12 weeks of age, 12 pounds, and who are not showing signs of rolling over.

We recommend using the Moms on Call swaddle blanket , designed for comfort and safety. Our swaddle blankets provide just the right amount of snugness without restricting movement, supporting healthy hip development. For those unfamiliar with swaddling, we have a helpful Moms on Call Swaddle guide that demonstrates the correct technique to ensure your baby is swaddled safely and securely.

Avoiding Overheating

A baby’s ideal room temperature is between 68-72°F. It’s essential to check for signs of overheating, such as flushed skin, damp hair, or sweating. If you notice these, remove a layer of clothing or adjust the room temperature to ensure your baby stays comfortable. Babies who are too warm may also be fussy, so monitoring their comfort levels can help guide your decisions on layering.

Safe Sleep Guidelines

To create a safe sleep environment, always place the baby on their back to sleep and use a firm mattress in the crib. Avoid placing loose blankets, pillows, or stuffed animals in the crib, as these can pose suffocation risks. Instead, choose safe sleepwear options like swaddle blankets for newborns (under 12 weeks of age, 12 pounds, and not showing signs of rolling) or footed pajamas for older babies. By following these guidelines, you help reduce the risk of Sudden Infant Death Syndrome (SIDS) and other sleep-related dangers.
