According to the NHS, a baby can stay in a car seat for as long as they are under the age of 12 months. After that, they should be placed in a rear-facing seat.
How Long Can a Baby Stay in a Car Seat NHS?
Most infant car seats can be used until your baby reaches the maximum weight or height limit for that particular seat. After that, you’ll need to switch to a convertible car seat or a booster seat.
According to the National Highway Traffic Safety Administration (NHTSA), all infants and toddlers should ride in a rear-facing car seat until they reach the maximum weight or height for that seat. Once your child outgrows the rear-facing car seat, they can ride in a forward-facing car seat with a harness.
The American Academy of Pediatrics (AAP) recommends that children ride in a rear-facing car seat until they are at least 2 years old. After that, they can ride in a forward-facing car seat with a harness.
Most car seats have weight and height limits that are listed on the seat. You can also find this information in the car seat manual. Once your child reaches the maximum weight or height for their car seat, it’s time to switch to a different type of seat.
If you’re not sure what type of seat your child needs, you can always check with your local car seat safety technician. You can find a technician in your area by visiting the NHTSA website.
What are the guidelines for car seat use for babies?
There are a few different things to consider when thinking about how long your baby can stay in a car seat. The NHS recommends that babies should be kept in a rear-facing car seat for as long as possible, as this is the safest position for them to be in. However, there are a few other things to consider as well.
For example, if your baby is under 6 months old, it should not be in a car seat for more than 2 hours at a time. This is because they can get very uncomfortable in this position and it can put a strain on their neck and back. If you are going on a long journey, it is best to stop every 2 hours and let your baby out of the seat to have a stretch and a nap.
Another thing to consider is how big your baby is. If they are over 20 lbs or 9kg, they may be too big for some rear-facing car seats. You will need to check the weight limit of your seat before using it.
In general, it is best to keep your baby in a rear-facing car seat for as long as possible, as this is the safest position for them to be in. However, there are a few things to consider as well, such as their age, weight, and how long you will be traveling. By following these guidelines, you can ensure that your baby is safe and comfortable when traveling in the car.

The NHS recommends that babies should not be in a car seat for more than two hours at a time. This is to reduce the risk of them developing a flat head (plagiocephaly).
If your baby needs to be in a car seat for longer than two hours, you should stop for a break every two hours to give them a chance to move around and stretch their legs.
It’s also important to make sure that your baby’s car seat is properly installed and that they are strapped in correctly. You can find more information on how to do this on the NHS website.
What are the risks of leaving a baby in a car seat for too long?
It is never safe to leave a baby in a car seat for extended periods. There are many risks associated with doing so, and it can be extremely dangerous for the child.
One of the biggest risks is that the child could develop hypothermia. This can occur when the child is left in a car seat for a long period, as the seat will not provide enough warmth. The child could also develop dehydration if they are not given enough fluids.
Another risk is that the child could suffocate. This can happen if the child’s airway becomes blocked by the car seat. If the child is not properly secured in the seat, they could also be thrown from the seat in the event of a collision.
It is also important to note that leaving a child in a car seat for extended periods can be extremely stressful for them. This can lead to the child developing anxiety or behavioral problems.
In short, there are many risks associated with leaving a baby in a car seat for too long. It is important to make sure that the child is properly secured in the seat and that they are not left in the seat for extended periods. If you have any concerns, it is always best to speak to a doctor or other medical professional.
