Rear facing carseats for small cars? (Not infant!)

me

Hello! My daughter is going to be 11 months soon and she’s almost too tall for her infant car seat (evenflo safemax) I’m looking to get another car seat but we have a small car!

A lot of the one’s I’ve seen have been HUGE. Bonus points if it fits well with other seats as I’m going to have 2 under 2!

Thanks in advance!!
