I feel an idiot asking this as it must crop up all the time, but what do you do about the whole car seat situation when hiring a car abroad or getting a taxi? We're looking at doing our first flying holiday this year when DS will be just about 2. There's likely to be driving involved, even if just the transfer from the airport, but obviously not in our own car. So what does everyone do? Do hire company's provide car seats then? I just don't get it.
