Keeping Your Baby Comfortable: Safe & Gentle Sleep Tips for Room Temperature

One of the most common worries parents have, especially as the seasons change, is whether their baby is too hot, too cold, or "just right" for sleep. Unlike adults, babies can't easily regulate their body temperature, so they depend on us to create a safe and cozy environment for them. The good news? With a few simple adjustments, you can keep your little one comfortable and sleeping more peacefully year-round.

Why Room Temperature Matters for Baby Sleep

Newborns and young children are more sensitive to changes in temperature than adults. Being too hot increases the risk of overheating, while being too cold can make it harder for babies to settle and stay asleep. Creating the right sleep environment not only helps your baby rest better but also supports their safety.

Ideal Room Temperature for Baby Sleep

Most sleep experts recommend keeping your baby's room between 68-72F (20-22C). This range strikes the balance between being cozy and safe. A simple room thermometer can help you keep track, especially during seasonal shifts when your home may feel cooler or warmer at night. A ceiling fan or tower fan can help keep the room cool. Blocking drafty windows, and ensuring that heat sources are not blocked helps keep the room cozy warm. A good set of thick blackout curtains can help keep a room cooler during the days of summer months, as well as helping to keep warmth in during chilly winter months. Bonus, they also make the room extra dark for optimal sleep!

Proper Layering of Clothing

Think of your baby's sleepwear like your own: comfortable, breathable, and not too heavy.

• One extra layer rule: A good guideline is to dress your baby in one more layer than you would wear to sleep.

• Base layers: A soft cotton onesie or footed pajamas works well

• Seasonal Adjustments: Inc older months, add a sleep sack or wearable blanket for warmth, and a fleece pajama set if your house runs on the cold side. In warmer months, stick to lightweight breathable pajamas.

• Avoid overheating: Check your baby's chest of back, if they're sweaty, flushed, or have a heat rash (small red bumps all over the body that go away as baby cools off) they are likely too warm.

What to Use instead of Traditional Blankets

Loose blankets are not safe for babies under 12 months, but there are cozy, safe alternatives you can use!

• Sleep sacks (wearable blankets): These come in different thicknesses (measured in TOG ratings) for different seasons.

• Swaddles: For newborns, swaddling can be comforting, just be sure to stop swaddling once your baby is able to roll.

• Layered sleepwear: Combining light pajamas with a sleep sack is often enough, even in cooler homes. Again, the recommendation is one more layer than what is comfortable for you. (or consider a "thicker layer" such as fleece.

Keeping the Room Comfortable in Colder Months

When the temperature drops, here are some gentle ways to keep your baby's room cozy:

• Use a space heater with safety features (tip over and overheat protections), but never place it too close to the crib.

• Keep the crib away from drafts... try to avoid placing it directly under a window or near the vent if you can.

• Close curtains or blinds at night to help insulate the room. They also make plastic you can put over your windows to help keep cold drafts out of older homes/older windows.

• Consider a room thermometer/hygrometer to monitor both temperature and humidity, as dry air in winter can make sleep uncomfortable.

Gentle Encouragement for Parents

It's completely normal to second-guess whether your baby. is

too hot or too cold, every parent does! Trust yourself, and remember that a quick check (placing your hand on their chest or back) is often the best indicator. You're doing a wonderful job keeping your little one safe, warm, and loved.

When to Seek Extra Guidance

If you've tried adjusting clothing and room temperature and your baby is still struggling with sleep, there may be other factors at play. Gentle sleep shaping or personalized guidance can help you find more rest and peace of mind.

Keeping your baby comfortable doesn't have to be complicated. With the right room temperature, safe sleepwear, and cozy (but safe) adjustments during colder months, you can create a sleep environment that supports rest for the whole family.
