DS is 4.5 yo and is in an Evenflo Maestro and DD is 2 yo and in a MA, RF. Baby #3 is due in August and will be in a Chicco Keyfit. We have a Toyota Sienna with the 8 passenger option - 3 seats across in middle (middle seat can come out)and bench in back.
DS does not yet buckle himself, so I don't know if I want him all the way in the back, but I can't very well lift the infant seat into the middle. I also don't really want DD and DS right next to each other b/c I think they will fight like cats and dogs.
Any suggestions?
