okay mamas! I need recommendations!

I need recommendations on a carseat! I thought I was set on getting one that grows with baby, and will last until she's out of a booster seat completely, but then I got to thinking that I don't know if I want to carry her everywhere I have to go, especially is she's asleep (shopping, errands, ect)... lazy, I know.. now I'm back to square one because I don't want to spend $150 on a seat that will only last up to 30 pounds; only to fork out another chunk of chsnge for a seat that can be used after that... anyway, now I need recommendations and reviews on which carseat you used, and the pros/cons of it, and why! please 😘😘
