no extra charge, but be SURE that you state the age of the child. And be aware that the taxis--unless you insist otherwise--will use a "booster seat" integrated style (i.e. with the seatbelt as a restraint) from basically 2 years old on. Now, at 4.5 for our DS, it's no problem. But earlier it made me quite nervous. I also have not found any taxi to have a real car seat (i.e. for a baby out of the bucket, but not in a booster).<br><br>
Public transport is much easier, but there is no way I've found (maybe others have) to install a car seat in the bus.<br><br>
Good luck, where are you moving to?
