C.E.
we have 3 car seats in a dodge intrepid. utah law requires the infant car seat to be in the middle. it's not too bad to reach over a booster seat to put it in and out, it's just a little more nerve wracking to have our 3 yr old wait next to the car unattended while we do it. even though we could have fit the convertible seat for the 3 yr old, we figured a booster (with no back) would be easier because there is no bulky arm to lift up and down and possibly hit against the baby's seat. but it also means he can reach the baby easier, which is not always good. the other thing that changed when we put the third carseat in is that our 5 yr old could no longer get his own seatbelt on and off. that can be good or bad, depending on the kid. he was good about buckling and unbuckling himself at the right times, so we miss that.
