The Best Car Seats For Your 3-Year-Old Toddler
What Type of Car Seat Does a 3-Year-Old Need?
Most infant seats only accommodate children up to 30 pounds. Most children exceed the infant car seat weight and height maximums between two and three years. However, a booster seat isn’t the next step.
The American Academy of Pediatrics (AAP) recommends children ride rear-facing as long as possible. Additionally, it is advised that children use a seat with a harness until at least four years of age. This is why car seats for 3 year old child are often convertible car seats. Thanks to convertible seats children can ride harnessed and rear-facing up to four years old.
As your child grows the car seat transitions, growing with them and accommodating them until they are ready for a booster seat.
Other choices of car seat for age 3 are forward-facing seats. These seats are often more affordable but don’t allow your child to stay rear-facing.
Can my 3-year-old sit in a booster seat?
Once your child outgrows their rear-facing seat or infant seat, you may wonder can a 3 year old sit in a booster seat? It is not advised to put a three-year-old child in a booster seat.
Booster seats are belt-positioning seats that help the vehicle’s seat belt to fit across the child’s body properly. Most three-year-olds are still too small to use a booster safely.
Additionally, they are not mature enough to maintain the proper posture needed for a booster seat for the entire car trip. Booster seats are usually only appropriate for school-aged children.

How To Choose the Best Car Seat for 3 Year Old
Many parents put a lot of thought and time into choosing a car seat. You want your little one to be safe and secure when riding in a vehicle. However, there are also other factors to consider.
We have listed a few to help you get started brainstorming about your ideal 3 year old car seat.
- Car Seat Type. The car seat type for your child depends on their age and weight. You also want to consider the lifespan of the car seat compared to how much they will grow. Additionally, each state has laws and regulations about car seat safety and the AAP has recommendations as well. Most three year olds are definitely not ready for a booster seat and end up riding in a convertible seat or a forward-facing car seat.
- Car Size. You will want to think about the size of the car seat and how well it will fit in your car. Some convertible seats are quite bulky, with comfort features like cup holders that make them extra wide. If you have a small car you may want to consider a slim-fit seat or one that is designed for travel.
- Height & Weight Limits. The car seat you choose will need to be appropriate for your child’s size. Pay close attention to the minimum and maximum weight and height limits. Your child must meet the minimums for the seat to be safe. However, you don’t want them to exceed the maximums too quickly or you will need to buy another seat.
- Car Seat Weight & Size. Like most car seat types, there are a variety of sizes and weights when it comes to the best car seat for three year old. If you plan on traveling often or having to change vehicles, you might want a portable car seat for 3 year old. If you have a small car or need to fit three seats across you might want to check out small car seats for 3 year olds.
- Installation Type. Most car seats for toddlers over 30 lbs have both a LATCH installation option or a seat belt installation option. However, some car seats have weight restrictions on LATCH installation. Additionally, sometimes fitting three car seats across is not possible using LATCH. You should consider your unique situation when determining what type of installation your car seat will need to have.
- Safety. Safety is a top priority. While nearly all car seats are very safe, having to be NHTSA approved and crash tested, some go above and beyond. You can look for a seat with a steel frame, honeycomb interior design, or specially crafted crumple zones if you want it to be extra safe.
- Comfort Features. While age and weight limits are important you also want to check that the seat is comfortable for your kid’s body size. If your child needs to sit for a long time in the seat you want to ensure that it is comfortable, therefore you may need to check out the best car seat for tall 3 year old or a seat for kids with long legs. Getting in and out of the seat should also be easy for your little one, so consider the shape and size of the seat.
- Ease of Cleaning. One of the downfalls of toddler seats is that they aren’t as easy to clean versus infant seats. There are cup holders to worry about, fixed bases, and your child is probably messier than when they were a baby. Pay attention to how easy the seat is to clean, does it have rapid remove covers? Are the covers machine washable?
- Expiration Date. Always check the expiration date of your car seat. If you buy it new, this shouldn’t be an issue. However, you do want to make sure that its lifespan will last you until your child is ready for the next seat. If you are considering buying second-hand ensure the car seat is not expired and has not been in any accidents. Because you can’t guarantee the history of a used seat, it is usually better to buy new.
- Meet Safety Standard. Double-check that your car seat choice meets all safety standards set by the NHTSA. And is in accordance with your local state rules and laws.
- Price/Budget. Of course your price and budget matter too! Thankfully there is a wide range of price points.
- Accessories. Consider any extras that you or your child may want. This can include things like cup holders, armrests, or even snack cubbies.
