This is a really good one - notice the baby in the front seat, no carseat *gasp*...
Welcome to Argentina! Well, Latin America, in general.
This is how I brought Firstborn home from the hospital (only I figured I should at least sit in the backseat, just in case) - the boy never saw a carseat until we moved back to the States. That's just the way it is. Even if you can afford to buy one, a lot of cars just don't have seatbelts (and that's assuming you can afford to buy the car). And a lot of people will actually try to talk you out of using one. Oh, it happened to me, trust me. So good luck; and make sure you pray ~ a LOT!)
