7 Ways to Keep Kids Cozy and Car Seat Safe in Cooler Weather

When the temperature drops, parents face a tricky balance: keeping kids warm without compromising car seat safety. Puffy coats and bulky layers may seem like a cozy solution, but they can actually make a harness too loose, putting your child at risk. The good news? You can keep your little one snug and safe with a few smart swaps. Here are 7 car seat–friendly tips to help your family travel safely and comfortably this season.

1. Skip the Puffy Coats

Winter coats and snowsuits create dangerous gaps between the harness and your child. Instead, dress them in thin, warm layers that lay flat under the straps. A fleece jacket, thermal shirt, or lightweight sweater works perfectly.

2. Harness First, Then Blanket

If your kiddo needs extra warmth, buckle them into their car seat first, then place a blanket or poncho over the harness. This keeps the straps snug and secure while still giving them a layer to cuddle under. Pro tip: pack a favorite blanket in your travel bag so it’s always handy.

3. Choose Thin, Warm Layers

Layering is your friend! Think long-sleeve cotton tees, thin fleece pullovers, and cozy leggings or joggers. Multiple light layers trap heat better than one bulky piece and still allow the harness to fit properly.

4. Use Car Seat–Safe Covers

For babies and toddlers in rear-facing seats, a car seat cover that goes over the top (not under the child or between them and the harness) is a safe option. Look for styles that zip or snap around the seat, keeping your child warm without interfering with the straps.

5. Keep a Hat and Gloves Handy

Sometimes it’s the small accessories that make the biggest difference. Hats, mittens, and warm socks add comfort and warmth without affecting harness fit. Plus, they’re easy to remove once the car warms up.

6. Warm Up the Car First

Whenever possible, start your car a few minutes early to take the chill out before buckling your child in. A warm cabin means fewer layers are needed, and your child will be more comfortable from the start.

7. Pico Travel Tip: Pack Smart Warmth

If you’re traveling with the WAYB Pico Car Seat, cozy layers and portable blankets are a must. Since Pico is lightweight and compact, you’ll have extra room in your carry-on for fleece layers, travel-friendly blankets, and even our Pico Travel Bag to keep everything organized.

By dressing kids in thin, warm layers and adding blankets or covers after buckling, you can keep them both cozy and safe on every trip. Whether you’re heading to school drop-off or flying across the country with the Pico, these simple steps make fall and winter travel easier for the whole family.
