Car Seat Requirements To Leave The Hospital

It’s a day you’ll never forget! The day you bring your baby home for the first time! You will have made a lot of things and plans to do and are looking forward to introducing your new family addition to everyone.

But before, some basic rules will help you make your child’s first car trip happy and safe.

Do not forget that it is mandatory to use an approved car seat for your child, even if they are babies, and it has to be installed in the opposite direction of the travel way.  

Tip: It is a  good idea to try installing the car seat or carrycot before the baby is born, so you can be sure you can quickly and correctly fit it for your particular passenger when the big day finally arrives!

Hospital Car Seat Policy

As per the American Academy of Pediatrics (AAP), infants must sit in a rear-facing car seat or rear-facing convertible car seat ONLY from the moment they leave the hospital until they turn 2 years old.

Hospital car seats policy varies from one hospital to another.

Thus, calling the hospital before and getting a  better idea about their policy is the best thing to do to keep your baby on the safe side. 

Undoubtedly, car seat safety is the first and most crucial point to consider. Once it is time to go home with your baby, the hospital staff will ask you to bring the car seat to the baby’s room to be inspected by one of the nurses. Here, they will look at the overall car seat status, expiration date (usually within six years of the manufacturing date), and other features to ensure the baby is safe and comfortable. 

They will teach you how to place your little baby inside securely and comfortably. Then you will get a better idea of correctly installing the car seat in the car, which position is suitable for the baby’s age, and when to switch.

What kind of car seat is required?

Your infant must be seated in a newborn-compitable car seat or convertible car seat, have a 5-point harness and be in a rear-facing position.

Different Stages Of Car Seats

Stage 1 Car Seat 

This is the infants and newborn stage, where you must place the car seat in a rear-facing position. You must keep this position until your kid is around two years old. 

Stage 2 Car Seat

In this stage, you can place your kid in a forward-facing car seat and continue to do this until your child is around five years old. This is the favorite position for most kids, as they enjoy the ride while seeing you always, keeping them happy and safe!

Stage 3 Car Seat 

At this stage, your kid moves into a booster seat to support his entire body. These boosters are placed at the top of the car’s seat and secured with straps into the hooks. You can find different models in the market; some come with a back suppose, and some don’t only have the bottom part of the seat.   

Stage 4 Car Seat

It is also called the Seatbelt stage. As the name suggests, your child can sit like any other adult passenger in the car using the car’s actual seat – without any support- but with the seatbelt around to keep him secured and in place all the way long. 

Car Seat Parts

The main parts of children’s car seats are: 

Car Seat Armrests

This part of the car seat will add extra comfort to the kid, giving him good arm support all the way long. 

Car Seat Harness

The harness is the belt that secures the baby and keeps him in place while the car moves. Usually, it comes with an adjustable strap and lever to tighten based on the baby’s size and reach the proper comfort level.

Car Seat Buckle and crotch pad

The primary function of this part is to secure the baby and keep him in place all the time. 

Car Seat Chest pad

The chest pad offers the car seat harness an additional layer to avoid discomfort as much as possible. 

Car Seat Backrest

Keeping your kid comfortable is essential, and a car seat with good backrest support will make sitting there a good experience for your child. Usually, they come with lumbar support for extra comfort. 

Car Seat Headrest 

This piece gives your infant head support, especially during the first few weeks when he cannot support his head and body. 

Car Seat Handle 

The handlebar is usually adjustable to help you carry the car seat differently and goes both ways. The handle is practical to support some kinds of car seat covers and toys to give your kid extra joy!

Car Seat Base

This part sticks to the vehicle seat and stays there all the time. It attaches to the baby seat with built-in clutches that cannot be easily unattached – unless you press the button assigned to it. 

These are the parts that make out any child’s car seat. However, additional parts might be found in some models to keep your kid comfortable. For example, a car seat cover or shade canopy, which you can always purchase separately if the model you have doesn’t support them.

FAQ

Q1: How much does a car seat cost?

Children’s car seat prices differ based on the brand and features you are looking for. You might find basic car seats that offer the same safety as the most advanced ones. However, having extras make the ride more fun and comfortable for your kid. Usually, car seats price ranges between ~ $80 and $300, and some brands go beyond this price, offering a combo of car seat and stroller with some fancy finishings. 

Q2: Are built in car seats safe?

Like Dodge and Volvo, some car brands and models consider having built-in car seats in their designs to offer parents a more convenient design. They are all safe for kids of different ages. However, they have some cons to consider, like the lack of mobility, their location, and seat orientation. 

Q3: Do hospitals provide car seats?

No. Hospitals don’t provide you with a car seat to take it home with your baby. However, they might sell you some brands – if they have such offers, or they might give you some recommendations for local programs that offer car seats. To make bringing a newborn home from hospital a happy experience, we recommend you call the hospital before making any assumptions and be prepared to have one before leaving the hospital. 

Q4: What are the different stages of car seats?

There are four main stages for children’s car seats, including rear-facing, forward-facing, booster car seats, and seatbelts using the standard car seat.
