After looking at 15 options, I put together this collection of convertible car seats that grow with your little one from those first newborn days all the way to toddlerhood. Prices range from about $100 to $430, and you will find familiar names like Graco, Safety 1st, and Cybex, including the SlimFit3 LX, EasyTurn 360, Extend2Fit, and Grow and Go. When you are choosing, think about how much space you have in your back seat, whether you want a rotating seat to save your back, and how long the seat will actually last your child. These are the seats I would hand to a friend who wants one less thing to worry about.
