At the airport waiting to board.
Yes, I know that it's best for babies to stay rear-facing until they are two. And in my car, he will. But unfortunately this car seat doesn't do rear facing and it IS legal now to have him forward facing so that's the way it is. Miah found Shane a really nice car seat with lots of neat safety features and it's also the kind of carseat that grows with the baby (up to 100 lbs!) so this should work for a long time and many grandkids.
