Could anyone tell me if my tall, solid 7yr old DD (about 138cm tall last time I measured) needs a car seat in France? She usually uses a booster here, though I think she is just over the official minimum height limit for needing one. I've tried googling, but can't find what the minimum height/age/weight requirement is in France.
We're going to France by train in the summer and renting a car from the station. In the past I've had car hire companies try to charge huge amounts for rather basic and grotty child seats, if they actually have any at all. Do I need to book one for her? And if they don't have any in stock, do I need to go and buy one at the nearest hypermarket, or can we get by without? I don't want to have to take one with us on the train (well, several trains).
