How Many Car Seats Do I Need: All You Need To Know

By Jennifer Ward

I have seen many parents wonder, “how many car seat do I need”. Often parents think purchasing one car seat is enough, but as the baby ages, can you use the same car seat? Or do you need another car seat for your grown-up toddler?  

Usually, infant car seats are ‘rear facing’ and apt for babies up to 35 lbs. For toddlers, we need car seats that are ‘forward facing’ with a weight limit of up to 65 pounds. And finally, booster seat mode is for babies who have outgrown ‘forward facing’ car seats until a baby is ready for a seat belt. Considering there are different car seats/modes for babies of different ages, parents often get confused about whether a single car seat would be enough. Frankly speaking, the concern is justified. To meet all your queries, I have rounded up all you need to know about how many car seats a parent should have.  

How Many Car Seats Do I Need? 

How many car seats you should buy depends on several factors, like the number of babies you have, their ages, the types of vehicles you have, and how many cars you have.  

Usually, if you have a newborn, you will need a rear-facing infant car seat. When the baby turns 4 and up to 7 years old (40 – 65 lbs.), you would need a forward-facing car seat, and then finally, you can transition your baby to a booster seat until your baby is tall enough to use a vehicle seat belt without any assistance. If you have several cars, consider buying separate car seat bases to fit your car seat.

Factor Considering Purchasing Multiple Car Seats 

When buying multiple car seats, there are several factors that you need to consider. Peek at them before you decide:   


Car seats range from affordable to expensive models. However, purchasing multiple car seats could still be costly. So, you can consider a car seat under 100 that comes on budget and feature an all-in-one convertible car seat that you could use in multiple stages of baby’s growth.

You might already have a toddler who is using a booster seat. Now, if you welcome a new baby soon, you reasonably will need to purchase an infant car seat.  

Types of Car seat 

When buying car seats, keep in mind that there are different types, rear-facing infant car seats, convertible seats, booster seats, and all-in-one seats. Every type of car seat has pros and cons, so it’s essential to consider which seat will be best for you and your baby’s needs.   

  • If you have several babies who need car seats, buying individual car seats for every baby would be wise.

Advantages of Purchasing Multiple Car Seats  

  • Multiple car seats for several babies allow you to not worry about transferring the car seat between the vehicles and adjusting the setting every time. 
  • Purchasing multiple car seats designed according to babies’ age and weight ensures that your baby’s convenience and security are well taken care of.  
  • If buying multiple car seats of the same brand, chances are high that a single car seat base is compatible with all the car seats and makes it easier to install without much hassle.

Disadvantages of Purchasing Multiple Car Seats 

While purchasing multiple car seats can have its benefits, there are also some disadvantages to consider: 

  • Purchasing multiple car seats can be expensive. But there is no option if you have several babies of different age ranges. The cost of purchasing multiple car seats may strain your pocket. 
  • Some car seats are bulky and take up a lot of space on the vehicle, and multiple car seats might limit space for other passengers.  
  • Installing and maintaining several car seats can be a hassle and may take a lot of effort and time to maintain.  
  • Multiple car seats would need more space to store and add more concern for those living in small apartments.

Does my 8-year-old need a booster seat?  

Babies below the age of 8 should sit in a booster seat. However, if your baby is 8 years old and has reached the height of 4 feet 9 inches, then he can be secured by the car’s safety belt.  

Can a 4-year-old sit in a booster seat?  

Yes, 4 years old baby weighs above 40 lbs. and can sit in a booster seat. The baby has already outgrown the forward-facing toddler seat, so a booster seat would likely be comfortable.  

When can a child stop using a booster seat weight?  

Usually, when a baby is at least 4 feet 9 inches tall and weighs around 70 pounds, you can ditch the booster seat and start fastening the seat belt instead.
