We have a 2017 Chevy equinox. We’re really hoping to make this work as we wanted to wait 2 more years before trading it in. We don’t exactly need 3 seats across but there will be 3 kids in the back. Our son is 11.5 so he doesn’t use anything, our daughter will be 2 when the baby comes so I’m thinking a Diono for her and then possibly a Chicco Keyfit for the baby? I’ve read that the Chicco is the slimmest infant seat, any ideas of if a Diono and Chicco Keyfit will fit beside each other in the back? We want to have the 2 year old in the middle and the infant seat on a side and the 11.5 year old on the other side.
