We've got 3. We've also got a reasonably small car. (It's not as if we -knew- we'd get twins,
End-result ? The only practical way of transporting the three of them to childcare is having
the older one infront next to me, and the smaller twins in the back.
Offcourse a kill-switch for the passenger-airbag was a $75 fix, so it's not a big deal. Just
saying there -are- legitimate reasons for having a small child in front, sometimes.
