Winter Car Seat Safety Tips From Wee Learn & Play Childcare

Posted on October 25th, 2023

As the chilly winds begin to blow and the first snowflakes touch the ground, ensuring our little ones' safety becomes even more paramount, especially during car rides. 

Winter presents its unique set of challenges when it comes to child safety in vehicles. 

While it's tempting to snuggle them up in warm winter coats before buckling them into their car seats, this common practice might be putting them at risk. 

At Wee Learn & Play Childcare, our top priority is the safety and well-being of your children, both within our centers and beyond. That's why we're dedicating this post to educate parents about winter car seat safety. Based in Northwest Connecticut and serving the Torringford, Forbes, and Vogel-Wetmore School districts, we bring our expertise from years of childcare experience to ensure your little ones remain safe during the winter months.

The Danger of Winter Coats in Car Seats

When the temperature drops, it's only natural for parents to want to keep their children warm and cozy. However, the intersection of cold weather and car safety brings up some concerns that every caregiver should be aware of.

Understanding the Risks

While it might seem harmless to bundle your child in a thick winter coat before strapping them into their car seat, doing so can compromise the efficiency of the seat's safety features. Winter coats, especially those that are puffy or bulky, can create a misleading fit when you buckle the child in. Under the pressure of a collision, the fluff of the coat compresses, making the harness too loose to protect the child adequately. In severe cases, a child can even be ejected from their seat if an accident occurs.

The Harness Dilemma

The snug fit of a car seat's harness is crucial in ensuring a child's safety during transit. With a winter coat on, it becomes challenging to determine if the harness is tight enough against the child's body. When the harness isn't flush against the child, it fails to serve its purpose of securing them safely. It's a mistake that can have dire consequences, emphasizing the need for awareness and education on this topic.

Choosing the Right Jackets for Car Seats

As we delve deeper into the winter season, ensuring that our children are both warm and safe during car rides becomes a balancing act. While bulky jackets are a no-go in car seats, it doesn't mean you need to compromise on your child's warmth. It's all about making the right choices.

Selecting Safe Winter Attire

Opt for jackets that are thin yet insulating. Modern materials allow for slim designs without compromising on warmth. Fleece jackets or thin down jackets, for instance, offer warmth without the excessive bulk that interferes with car seat safety.

It's also a good practice to do the "harness test" with new winter attire. After putting the jacket on your child, strap them into their car seat and tighten the harness as you usually would. Now, without adjusting the straps, remove your child from the car seat, take off the jacket, and place them back in. If you can fit more than two fingers under the harness, the jacket is too bulky for safe use in a car seat.

The Layering Technique

Rather than relying solely on a heavy coat, consider layering your child's clothing. Start with a base layer, like a long-sleeved shirt, add a mid-layer such as a sweater or fleece jacket, and then use a thin, insulating outer layer. This method not only keeps your child warm but also allows for easy adjustments to their attire, ensuring they're comfortable and safe throughout the ride.

Key Winter Coat Car Seat Safety Tips

Understanding the danger of winter coats in car seats is essential, but it's also crucial to know how to ensure your child is safe. With a few simple tips and checks, you can guarantee their safety without forgoing warmth and comfort.

Harness Check: The Pinch Test

Every time you strap your child into their car seat, especially during winter, it's wise to perform the "pinch test." After fastening the harness, try to pinch the webbing at your child's collarbone level. If you can pinch the material and create a fold, the harness is too loose. Tighten it until you can no longer pinch any excess webbing.

Avoiding Aftermarket Products

While various products in the market claim to offer solutions for winter car seat safety, it's essential to be cautious. Items like padded strap covers, thick blankets under the child, or cushion inserts that haven't been crash-tested with the car seat can compromise its safety features. Stick to what's approved by the car seat manufacturer.

Staying Warm Without the Coat

One practical solution is to strap your child into their seat without their winter coat on and then lay the coat or a blanket over them, ensuring they're warm without compromising on safety.

Booster Seat Safety During Winter

As children grow, their safety needs in a vehicle evolve. Transitioning from a traditional car seat to a booster seat marks a significant step in a child's journey, but it brings its own set of winter challenges.

The Unique Challenges with Booster Seats

Unlike car seats, booster seats rely on the vehicle's seat belt to secure the child. However, winter coats can interfere with the proper positioning and snug fit of the seat belt. A bulky coat can push the shoulder belt away from the child's body, making it less effective during a collision. Furthermore, the lap belt might ride up to the stomach instead of lying flat across the upper thighs, increasing the risk of injury.

Strategies for Safe Winter Travel in a Booster

  • Seat Belt Positioning: Always ensure that the shoulder belt lies snugly across the chest and the lap belt across the upper thighs. If a winter coat is preventing this proper fit, it's too bulky to be worn in the booster.
  • Coat Reversal Technique: A handy trick is to secure your child in the booster seat without their winter coat. Once buckled in, take their coat, reverse it, and put it on backward (with their arms through the sleeves). This way, the coat acts as a blanket without interfering with the seat belt's fit.
  • Use Car Blankets: Keep a couple of warm blankets in the car. Once your child is safely buckled in, drape the blanket over them for warmth. It's an easy and safe solution to the winter coat dilemma.

Choosing the Right Safety Seat for Children

Every child's safety journey in vehicles is marked by transitions—from infant carriers to forward-facing car seats, to boosters, and finally, seat belts. Knowing when and how to make these transitions is crucial.

Determining the Right Seat

  • Age, Weight, and Height: While age can be a general guide, the child's weight and height are more accurate indicators. Always refer to the manufacturer's guidelines for the specific seat you're considering.
  • Rear-Facing to Forward-Facing: Experts recommend keeping children in rear-facing car seats as long as possible, ideally until they outgrow the seat's weight or height limit.
  • Transition to a Booster: After outgrowing the forward-facing seat, children should transition to a booster seat until they're tall enough to fit in a seat belt properly.
  • Seat Belt Readiness: Before allowing your child to use only the vehicle's seat belt, ensure the lap belt fits snugly across the upper thighs, not the stomach. The shoulder belt should lie snug across the shoulder and chest and not cross the neck or face.

Professional Installation and Checkpoints

To be doubly sure of your child's safety, consider having their car seat or booster seat professionally installed. Many local fire stations and safety organizations offer this service for free. Regularly attending car seat checkpoints or safety events can also ensure that your child's seat meets current safety standards.

Your child's safety is a continuous journey, but with the right knowledge and tools, you can ensure they're protected every step of the way.


Winter brings about a magical transformation, with its snowy landscapes and festive celebrations. But amidst the enchantment, it's essential not to lose sight of the unique challenges the season poses, especially concerning our children's safety during car travels. Bulky winter coats, while warm, can compromise the efficacy of car seats and booster seats. The risks are real, but armed with the knowledge from this guide, you can navigate these colder months with confidence.
