here's my situation. i have three kids, three carseats, and i drive a honda odyssey.
my 4yo is FF in a marathon in the middle of the third rwo
my 2 1/2 yo is RF in a marathon on the drivers side of the middle row (captains chair)
my 10 mo is RF in a companion in the middle of the second row (pass side captains chair moved over)
my 10mo will probably be outgrowing his companion sometime, though he's pretty petite, only 18 pounds and has a few inches between the top of his head and the top of the seat. i would like to get a new seat for him pretty soon.
my original thought was to give him my 4yos marathon, and get my 4yo a regent, but my 4yo is pretty petite too. Only 34 pounds and about an inch below the third slots. I think he will get a good bit more time in the marathon and he looks so tiny in the regent.
I do have the eighth plus one seat for my Odyssey, and it would be great if i could put three seats across. I was thinking maybe a radian?
my husband is sick to death of hearing about it, so i'm hoping for some input here.
