Help! My infant is already the height limit for our car seat.

Haily • 19 •Baby boy arrived July 29, 2018👶🏻💙👣

So my little guy is already 30 in tall. And we have a 2 door car so a convertible car seat would just be a hassle(id have to get in and put him in every time).

Is there any nonconvertible car seats that have a taller height limit. Anything helps. Thanks❤️
