Choosing Your Car Seat

Since your child is at an age where they are still growing quite rapidly, you want to make sure that whatever car seat you choose is going to last through any sudden growth spurts. Typically, the best kind of car seats for this purpose are boosters or convertible seats, as many of them can be transformed into boosters as your child ages to better prepare them for the transition into a regular car seat.

Booster seats are necessary for children between 40 and 100 pounds as they are generally too small to effectively utilize your car’s seat belts until they’re about 8 years old or about 4 foot 9 inches.

Improper fitting of seat belts can cause serious injuries to your child should you be involved in an accident so it’s best to be cautious and do your due diligence when selecting a booster.

High Back Booster

High back boosters include head and neck support and may even have adjustable headrests built-in for ease of use. If your vehicle has low seat backs, these types of boosters will provide your child with the necessary support they need. Depending on the type of booster you choose, it may also come with anchors that can be helpful to further secure the booster to your vehicle.

Backless Booster

Depending on your needs, a backless booster may do the trick for your child. If your vehicle has solid head support and higher back seats, then a backless booster is generally sufficient.

All-In-One Car Seats

All-In-One or Combination car seats can normally be used as a booster simply by removing the included harness, but this varies depending on make and model so be sure that it suits your vehicle’s and toddler’s specific needs before committing to one.

If you’re still unsure of what kind of safety seat is best for your needs, the American Academy of Pediatrics has a conclusive product listing of available options that are organized quite handily by restraint type and includes height and weight requirements, so cross-reference their listing with the models you’re interested in.

Tips For Buying Your First Car Seat

Don’t Rush Out To Buy On Their Birthday

Just because your child is now four years old doesn’t necessarily mean that you need to immediately switch them to a new car seat. If your child hasn’t hit the weight or height requirements yet, keep them in their current restraint. That being said, if your three-year-old has quickly hit the weight requirement, it’s certainly time to start looking at your options.

Test the Fit

Your child is going to be using this car seat for a long time, so if you have the opportunity to go test out some floor models, do take the time to do so. See where the lap belt falls on your child in different models because in the event of a crash a belt that falls on the abdomen instead of the thigh is not going to be absorbed properly to protect your child from injury. The straps should fit snugly on your child, not too tight or too loose.

Measure Your Backseat

Some car seats are a lot bulkier than other car seats, so if you have a compact car with limited backseat space, you may have to limit your search to slimmer models. Also be sure to consider and check that you still have ample room for any other people that may be riding in the car at the same time as the car seat is installed.

Retailing for only $450.00 with a lifespan of ten years and the ability to be transformed to follow a child’s growth from infantry to 120 pounds make the Graco the best car seat for 4-year-old children and beyond.
