Hi, hoping an MNer in Italy can help, we are flying to Pisa in the summer and I need to know about child seat requirements in cars. Dd1 is 9 and tall for her age (at least 139 cms) so doesn't legally need a car seat in the UK. We have a trunki back pack thing that converts to a car seat but she would prefer not to take it. What are the rules? I've googled but the results were ambiguous and/or contradictory.
