I apologize if this is a double post, I searched and couldn't find one! I'm wondering how all you ladies are arranging your car seats? I have twins who are 19 months and the new baby. The twins are just starting to help themselves in (put their arms through the straps). I have a minivan, and as of now the twins are rear facing in the captains seats in the second row. Trying to decide if we should move both older kids to the third row? Or just one? Anyone else with three rear facing seats?
