I don't think that it's a great idea two have two adults and a baby (and seat) in a teen, even if you add an extra set of belts. Pick up a baby seat, those things are huge.

In Ontario, Canada, it's no problem for one adult and a baby, as the car is a two seater and it has no air bag. I've thought about adding extra seat belts, so that I can take my two kids (when they both out of baby seats) in the car, but I will find out if it's legal first.

What ever you decide you should go to your local police station, and ask them to look at your car/car seats etc. and they can tell you if it's legal or not. You may need an appointment and sometime's the police (here) run baby seat clinics.

This is the safety of your child, so take care and do it right. Good luck with your new baby. Mark
