Hi. Our infant car seat has expired and we will need a new one for LO #3. We previously had a Graco SafeSeat and it was fine, very easy/user friendly and compatible with our Maclaren Snap n Go but HEAVY! Any recs for a lightweight seat, that is narrow (I have a Sienna but DH drives a truck with a club cab so we'll need to be able to fit a convertible, infant seat, and booster across) that will work with our Maclaren Easy Rider? From what I can tell online, the Chicco KeyFit should work......any feedback or alternate suggestions? TIA!
