Best mom car!
Whatever works for your family! There are many different situations for different families. A family with one child will have more options than a family with 3 or more children to tote around. one thing you have to consider is will the car seat fit in the car? I know i had a four door car with my first baby and the infant carrier car seat was a bit loose when we attached it so we had to get a bolster (or pool noodle like item) to put under the car seat to help tighten the seat. But when I had more children i could not fit the car seats in the back seat of the car so we had to graduate to a larger vehicle! So in essence ... all families are different as are their car needs... just make sure you have room for car seats and space for groceries and diaper bags!
