Help! Which Car Seat Should I Upgrade My 11-Month-Old To?
Share
If you're staring at car seat options feeling completely overwhelmed, you're not alone.
Your 11-month-old is outgrowing that infant capsule, and now you need something that will keep her safe, comfortable, and last for years. Let's cut through the confusion.
The Short Answer: You Need a Convertible Car Seat
At 11 months, your daughter is ready to move from an infant capsule to a convertible car seat. These seats are designed to stay in the car (unlike the portable capsule) and "convert" from rear-facing for babies to forward-facing for toddlers.
But here's the most important thing Aussie parents need to know:
Safety experts recommend keeping your child rear-facing until at least 2 years old, preferably longer. So whatever seat you choose, make sure it supports extended rear-facing.
Our Top Pick: The Britax Safe-n-Sound Graphene


After researching options in the same price range, the Britax Safe-n-Sound Graphene Convertible Car Seat stands out as the best value for Aussie families.
Why it's the winning choice for your 11-month-old:
- Extended Rear-Facing: Keeps her rear-facing from birth up to 4 years (hello, safety!)
- Forward-Facing Mode: Then converts for toddlers up to 4–8 years
- Lightweight Design: At only 7.4kg, it's one of the lightest convertible seats — easy to move between cars
- Aussie-Approved: Meets strict Australian Standard AS/NZS 1754
- Deep Side Wings: Extra head and side impact protection
- Easy Install: Click & Safe technology confirms correct installation
The best part: You buy ONE seat that takes you from now until she's ready for a booster. That's real value.
