When choosing between an infant car seat vs all in one , it’s easy to feel torn. Infant car seats are designed specifically for newborns, offering a snug and secure fit for early months.
Different from other car seats, all-in-one seats change with your child, going from rear-facing to forward-facing and then to a booster seat.
They are popular for long-term use because they are flexible but bigger and harder to move around than baby seats. To make an informed choice, you need to know the differences between these two types of car seats.
Whether you’re a first-time parent or a seasoned caregiver, this guide will help you navigate the pros and cons of each option to ensure your child’s safety on the road.
To help you make the best decision, we’ve compared these car seat types across critical factors like safety, convenience, cost, and longevity.
What Is an Infant Car Seat?
Infant car seats are rear-facing car seats designed for newborns and infants. They often come equipped with click-and-go bases, allowing easy transfer between your car and a compatible stroller. Most infant car seats accommodate babies up to 30-35 lbs or around 12 months old (depending on the model).
Best For: Newborns and families that prioritize portability.
Pros:
- Perfect Fit for Newborns: Infant seats accommodate little newborns snugly for safety and comfort.
- Portability: The click-and-go functionality makes moving your baby easily without waking them.
- Lightweight: Infant seats weigh less than convertibles, making them easier to carry.
- Compatibility with Strollers: Many infant car seats attach to strollers, doubling as a travel system.
Cons:
- Limited Longevity: Once your baby outgrows the weight/height limit, you’ll need to purchase another seat.
- Additional Cost: You’ll eventually need to invest in a convertible car seat, which increases overall spending.
It is ideal for families who are frequently on the go or need maximum convenience when traveling with an infant.
What Is an All-in-One Car Seat?
All-in-one car seats are designed to grow with your child, converting from a rear-facing seat for infants to a forward-facing seat and eventually to a belt-positioning booster. They provide long-term car seats for youngsters 5 to 120 pounds.
Best For: Families looking for an affordable, one-time investment.
Pros:
- Versatile: Covers all stages (infant to booster), eliminating the need to buy multiple seats.
- Cost-Effective: Saves money in the long run compared to purchasing different car seats for each stage.
- High Weight Limits: Many versions fit taller, older children and offer longer rear-facing alternatives for safety.
Cons:
- Bulkier Size: All-in-one seats tend to be heavier and more challenging to move between vehicles.
- Fit for Newborns: Some models may not provide an ideal fit for very small infants, even with inserts.
- No Click-and-Go: These seats are not portable and must stay in the car at all times.
Great for families who want a long-term, no-fuss car seat but might not prioritize portability.

Making the Right Choice: Which One Should You Choose?
Several key factors must be considered when choosing between an infant car seat vs an all-in-one car seat.
Baby’s Age and Size: Infant car seats are ideal for newborns and babies up to 12 months, offering a secure, snug fit. Once your child outgrows the seat, it’s time to transition to a larger option, like an all-in-one car seat, which grows with your child, lasting well into their toddler and booster seat years.
Lifestyle: If you’re always moving, an infant car seat may be better. Small, light, and portable, it fits into travel systems. For a long-term solution, an all-in-one car seat may be ideal since you won’t need to upgrade.
Car Size: Small cars may benefit from infant seats’ compact designs, while larger vehicles can accommodate the bulkier all-in-one models without taking up too much space.
Real-Life Scenarios: Consider your daily routine. Parents who drive long distances or have multiple children may enjoy an all-in-one car seat because it’s versatile and durable. For city parents or those who need a car seat for short journeys, an infant seat may be more portable.
Our Recommendation
An Infant car seat is the safest, easiest, and most portable way for families who care about safety to travel with a newborn. An all in one car seat, on the other hand, is the best choice if you want a cheap option that will last and cover all stages. Still not sure? Visit a store near you that sells baby gear and try both types in your car. Every family has different needs, and the best car seat for you is the one that works best with your lifestyle.
Conclusion
Finally, your family’s needs will determine whether you should choose an Infant car seat or an all in one car seat. Infant car seats are great for babies because they are small and easy to use, especially when traveling. They are limited in use and require an upgrade once your baby outgrows it.
On the other hand, all-in-one car seats provide long-term value by growing with your child from rear-facing to forward-facing and eventually as a booster seat. While bulkier and less portable, they save money in the long run.
Ultimately, the choice depends on your lifestyle and whether you prefer a convenient, short-term solution or a versatile, long-lasting investment. Both options prioritize your baby’s safety and comfort regardless of your choice. Weigh the pros and cons to determine the best option for your family, considering the infant car seat vs all in one decision.
