How to Help Your Baby Adjust to Seasonal Weather Changes

Spring into Comfort: Preparing for Warmer Days Ahead

April is here, and with it comes the promise of warmer days, blooming flowers, and longer evenings. As winter fades into spring and summer edges closer, many parents wonder how best to keep their baby comfortable through the changing weather. Infants are especially sensitive to temperature fluctuations, and adjusting your routine to the season is key to keeping them safe, cozy, and content.

Your Baby’s Built-In Thermostat Needs Help

Babies, especially newborns, aren’t great at regulating their own body temperature. They can overheat or get chilled much faster than adults, which makes this time of year—when mornings can be brisk and afternoons sweltering—a bit tricky. Being aware of your baby’s cues and making thoughtful adjustments to their environment and wardrobe can make a big difference.

Springtime Dressing: Layers Are Your Best Friend

This is the season of “sun’s out, coat’s off, clouds roll in.” The most effective way to dress your baby during this transition is with breathable layers. Start with a cotton onesie or bodysuit and add a light cardigan or long-sleeve layer that’s easy to remove. Keep a sunhat and a light blanket handy in your diaper bag—you’ll use them more than you think as you move in and out of sun and shade.

As the weather continues to warm, switch to lighter fabrics like cotton and muslin to avoid overheating. Avoid heavy knits or fleece, and instead opt for soft, airy materials that allow heat to escape.

More detailed clothing tips and temperature guidelines can be found from Lancaster General Health, which notes that babies generally need one more layer than an adult would wear in the same conditions.

Monitor for Overheating (and Overcooling)

During spring outings, it’s important to frequently check your baby’s temperature—not with a thermometer, but with a gentle touch. If the back of their neck feels sweaty or damp, they may be too warm. Cool hands or feet, on the other hand, don’t always mean your baby is cold, but cold chest or back skin is a better indicator that another layer might be needed.

Safe Sleep, Even as Nights Warm Up

Room temperature is just as important as what your baby wears to sleep. As we shift toward summer, your baby’s sleep environment should be kept between 68–72°F (20–22°C). If you don’t have air conditioning, using a fan to circulate air can help—just make sure it’s not blowing directly on the baby. Ditch the heavy sleep sacks or blankets and move to a lightweight wearable blanket to keep your little one secure and cool.

Springtime Protection from the Elements

With more time outside, spring presents new environmental challenges, especially sun exposure. Babies under six months should be kept out of direct sunlight, according to pediatric guidelines. Use stroller canopies, sunhats, and lightweight clothing with long sleeves and legs to protect delicate skin. And don’t forget bug protection in the form of mosquito netting and appropriate repellents (check with your pediatrician for safe options).

As we move into summer, hydration becomes key. For babies who are still exclusively breastfed or formula-fed, additional water isn’t usually necessary, but frequent feeds are. If your baby is older and has started solids, your doctor may recommend offering small sips of water in hotter weather.

Consistency Amid Change

While you may be adjusting your baby’s clothing and outdoor routine, it’s helpful to keep feeding, naps, and bedtime consistent. Babies thrive on predictable patterns, and having some stability as the world around them shifts can be grounding for you both.
