Taking the lil one to BKK for vacations. I'm thinking of babywearing him instead of using a pram but not quite sure how to sort out the car seat issue when traveling by car. How did you all do it?

I don't have a car as well. When I travel in a cab, I make sure I'm baby-wearing and have my seatbelt strapped on. A baby carrier is not a safety device and does not replace a car seat, but it's better than just carrying the baby in your arms because the baby might fly out of the windscreen in case of a crash. Otherwise, you could get a pram with a car seat adaptor like a Quinny. http://www.quinny.com/us-en/accessories/maxi-cosi-mico-ap/
