How to dress baby in 50 degree weather: chilly mornings, mild afternoons

Figuring out how to dress baby in 50 degree weather mostly means getting through a day with two seasons in it. At 9 a.m. it feels like 43 °F with wind, at 1 p.m. it’s 63 °F and sunny, and in between you’re sitting on a warm bus. Spring is similar, except the sun gets strong before the air warms up. Here’s when a light jacket is enough and what comes off along the way.

Chilly morning, mild afternoon: how to dress baby for a walk

Dress your baby for the coldest hour you’ll spend outside: a onesie, at most one warming layer and, as soon as it’s cool or wet, a light jacket or a suit. From a feels-like 50 to 67 °F (10 to under 20 °C), add a thin hat; below that, a warm one. Wind counts too: at 37 °F (3 °C) with a 12 mph wind, it feels like about 29 °F (−1.5 °C).

If your walk spans two times of day, say 9 a.m. to 1 p.m., go with the outfit for the colder one. The baby weather app BabyWear shows it to you for morning, midday and evening, with wind, rain and UV index.

As it warms up, the top layer comes off first: fold back the blanket, unzip the jacket or suit. Then feel the back of your baby’s neck: warm and dry means just right, sweaty means one layer less. Cool hands are normal.

How to dress baby in layers: thin ones, only one warming layer

Dressing in layers doesn’t mean three sweaters on top of each other. It means thin layers that each have one job:

• Base layer: a onesie or shirt right against the skin.
• Warming layer: at most one, so a footie, a sweater or a cardigan.
• Outer layer: a light jacket or suit as soon as it’s cool or wet. It’s the first thing you open at noon.
• Head, hands, feet: a hat, socks, and mittens when it’s cold.

What about “one more layer than you”? That only applies below 59 °F (15 °C), and only for a baby lying or sitting still in the stroller: then at most one extra layer on the upper body. Otherwise your baby wears no more than you do, and from 3 months that goes for indoors too.

Light jacket or fleece suit? How to dress baby in 50 degree weather by age

It depends on age: Up to 5 months, a light jacket is only enough from a feels-like 59 °F (15 °C); below that, your baby goes into the wool fleece suit, a one-piece fleece bunting. From 6 to 17 months, the jacket plus a sweater works down to 50 °F (10 °C), and from 18 months down to 41 °F (5 °C). In the stroller, a baby makes far less body heat than a child who’s walking.

Suit or light jacket by age: feels-like temperature, dry, wind under 9 mph, normal warmth sensitivity; the suit is the outer layer. Up to 2 months, the cardigan is the warming layer at 41–49 °F, and from 6 to 11 months, add a light blanket at 50–58 °F. Plus socks, shoes from 12 months, and winter booties below 50 °F.

Below a feels-like 41 °F, add mittens and a footmuff; in rain or wind, the mittens go on below 50 °F already. More in how to dress your baby for winter. Every step from 77 °F down to freezing: how to dress your baby for the temperature.

In rain or in wind from 9 mph, babies up to 5 months swap the footie and wool fleece suit at 50–58 °F for pants, a cardigan and a softshell suit. The stroller rain cover goes over the outfit only while it’s raining, never in place of a warming layer, and with the vents open. More in out in the rain with your baby.

Which hat does your baby need in the fall?

Below a feels-like 50 °F, the warm hat; from 50 to 67 °F, the thin beanie, even in sunshine. The sun hat (from 18 months, a cap with a neck flap) only comes out from a feels-like 68 °F (20 °C) with real sun, and never two hats at once.

In wind, a hat over the ears matters more than another middle layer. Indoors, in the car and in bed, every hat comes off, even in a cool room.

How to dress baby in spring: strong sun, cool air

In spring, the temperature is deceiving: the UV index usually hits 3 by April, and light clouds don’t block much. Still, below a feels-like 68 °F the hat stays on, the thin one from 50 °F. Sun protection comes from the canopy, shade and thin, long clothing.

In the first year, your baby doesn’t belong in direct sun, and you avoid sunscreen. Never drape a cloth over the stroller, because heat builds up underneath.

How to dress baby in fall: wind, fog and early darkness

In wind, the outermost layer has to be windproof, with knits and fleece underneath. Turn the canopy into the wind, use the footmuff instead of a blanket below 50 °F, and never put anything over your baby’s face or the stroller opening. Hot-water bottles and microwavable heat packs don’t belong in the stroller.

It cools off fast after sunset, so check the evening forecast for the walk home. In fog and darkness, light-colored clothes and reflectors help. Drizzle and fog aren’t great outing weather with a newborn; if you do go out, use the footmuff.

On the bus and at Grandma’s: unzip the suit right away, even if baby’s asleep

Yes. On the bus, in a store and at Grandma’s, the hat and mittens come off, and the jacket, suit and footmuff get opened right away, even if your baby is asleep; at Grandma’s, they come off completely. In the car, take off the suit and footmuff before buckling up, and lay the blanket over the snug harness. Indoors is where babies are most often overdressed.

If Grandma keeps it at 72–75 °F (22 to under 24 °C), a short-sleeve onesie and light pants are enough at 3 to 5 months; under 3 months, add a long-sleeve shirt. Then check the back of the neck.

How to dress a toddler in fall: daycare and the playground

From 18 months, the threshold shifts, even if your child started walking earlier: the winter coat, snow pants, mittens and winter boots only come out below a feels-like 41 °F. Daycare drop-off at 39 °F and pickup at 61 °F are two outfits, not one compromise.

During really wild play, the sweater can come off, and it goes back on afterward. Change wet socks right away, because wetness chills even above 32 °F. Puddles aren’t in any forecast: from a feels-like 50 °F, rain pants go over the regular pants; below that, lined ones.

Heat on: lighter indoors, sleep sack by the room

Once the heat is on, your baby tends to need less indoors: on a cool fall day, the living room sits at an estimated 68 to 70 °F (20–21 °C), and at 3 to 5 months a long-sleeve onesie, pants and socks are enough.

Choose the sleep sack by the room, never by the calendar. At 64–67 °F (18 to under 20 °C), a 1.0 TOG sleep sack over a long-sleeve onesie and pajamas is enough; only below 64 °F does the 2.5 TOG winter sleep sack come in. TOG tells you how warm a sleep sack is. BabyWear shows you the TOG rating for the room temperature you measure at the crib and enter in the app. More on choosing a sleep sack by temperature.

In the crib: no hat, no blanket, no socks, not even with a cold. For naps, take off the cardigan and socks from the day.
