Ditto.... 3 in 1 seats are marketed quite well yet we consider them to be Jacks of All Trades, Masters of None

Also, please visit my website (page: "Newborns -- Preschool") link in signature to learn why 12 months is no longer the standard recommendation to turn forward.
The American Academy of Pediatrics & Safe Kids urge parents to keep kids
RF until the maximum weight or height limit of their
convertible seat, which may be at least a year or more after baby's 1st birthday.
The seat you have generally works well
RF, but the majority of kids outgrow it's harness
FF long before they are truly ready for
booster use & as a
booster, this seat pales in comparison to more dedicated options. This seat will also likely expire before kiddo is able to safely ride without a
booster. I personally would only use this seat
RF and/or only as a spare.
Have you checked the database yet to see which carseats fit your vehicle?
