We all want to make sure that our children are safe and sound, no matter where we are. That's why I now began focusing on how I can help protect my children, particularly during car rides! It's important to have a quality car seat for your little ones to avoid anyone moving around and creating any accidents. Plus, it protects them from any injuries if anything bad happens while on the road.

I've done my research and found a ton of car seats, but what caught my eye was the Diono Radian RXT car seats. There are a ton to choose from, all having the quality material and strength!

If you're wondering which is best for you, then read on as I show you the seven best car seats from Diono!

Why Choose Diono Car Seats

You're probably wondering: Why bother investing in a car seat in the first place? Well, if you're a family who loves long drives (or even short ones around town), then you'll find a car seat beneficial in all ways.

Here are some of the benefits it has to offer:

Protection and Required By Law
That's right, car seats are usually required by law in various states, all for the sake of your baby's protection! With a quality car seat with comfortable harnesses and buckles, your baby will be safer and less susceptible to any injuries if accidents ever come its way. Plus, they remain comfortable and fit in the car seat, rather than move around or fall off the big seatbelts!

Free From Accidents In the Car

No one wants a curious baby roaming around the car and causing trouble. Not only will this make a mess in the car, but your baby might get hurt from moving around too much, which makes it even more troublesome for the parent. That's why it's best to strap them in so they stay in one place and no accidents (may it be from their curiosity or in the diaper) will happen.

Keep Your Little One Entertained

Last but not the least, many car seats come with compartments and options which allow you to install toys for your little one to enjoy. That way, they will be quiet and calm throughout the car ride, which makes us focus on driving safely. Anyway, no one wants to deal with a hysterical baby when you can entertain them with good toys!

How to Choose Quality Car Seats

You won't be able to reap the benefits of a car seat if you don't choose the right one for you and your baby! Because there are a ton of car seats available under Diono alone, it can get quite confusing choosing what's ideal. To help you out, here are some tips and factors to consider:

  • Type of Car Seat
    There are three different types of car seats to choose from, all depending on your little one's age and size:
    Infant car seats are light and portable, which can be clipped in your car or strollers. These are rear-facing car seats, as it's the safest position for newborn babies. Usually, they would outgrow this seat when they reach a year old. These are best for those who need something portable and can be clipped to strollers.
    Convertible car seats can either be rear or front-facing, hence the name convertible. They can either be used from birth or up to when they are toddlers, even converting to a booster seat. But, they can be too heavy and can't be clipped on to strollers.
    Booster car seats are for small children who outgrow the infant car seat but can't use the adult-sized seat belts yet. These are for children 40 to 65 pounds and can be used until they are 12 years old.
    Also, check out your local regulations and laws on this to ensure that you choose the right car seat for your baby's size and age.
  • Baby's Age, Weight, and Height
    Consider your baby's age, weight, and height to ensure that they are comfortable and that the seat isn't too tight or loose on them. They need to feel good throughout the ride to avoid any injuries.
    Also, consider the car seat's size. It must fit your car, with it not being too big to install. You can measure your car seats beforehand and get the dimension of your chose baby seats to ensure that it fits.
  • Car Seat's Safety Features
    There are three crucial features you should look out for, which are:
    • The car seat should have a 5-point harness, which is two shoulder, two waist, and between-the-legs straps which meet in the middle buckle to hold your baby in place.
    •It should also have side-impact protection and bumpers for better protection and to keep your baby comfortable.
    •Also, look out for an easy harness adjustment to make it hassle-free for you and safe for your child.
  • check
    Ease of Installation and Cleaning
    Finally, you'll definitely want to focus on a car seat that's hassle-free for you, too! So make sure that the car seat is easy to install alone (or with your partner), as well as it is easy to clean.
    I look for car seats that take no trouble to install and adjust so car rides won't be too much of a tedious task. Plus, I like seats with smooth fabrics to wipe it easily, compared to the absorbent and textured fabrics! Or if you anticipate a lot of messes, having a removable machine-washable cover helps. 

Bonus Tips on Traveling With Your Little One

Now that you're familiar with how to choose a quality car seat, how will you be able to travel with your little one using it? Here are some tips on how you can travel with your baby by car with the help of the car seat:

•   I recommend that you install the baby seat in the middle position of the back seat. That's because it's farthest from the doors and windows which may break from a crash. Never put the rear-facing car seats on the passenger seat, especially when it has an active airbag.
•   Dress up your child in clothes that keep a tight fit in the seat's harness. When it's cold, put your little one without a coat then place the coat or blanket over him when he's buckled in his seat.

•   Keep your little one comfortable and entertained with books, his favorite toys, or safe snacks that won't easily spill or crumb around. Music also helps calm them down if they cry in the seat!
•   To avoid screaming babies or those who love to move around and make a mess, travel at the right time, when they are at their happiest! This may be going on car rides after eating, if they are still drowsy, or after a full nap.
