Hi, we are hoping to go to Europe on holiday in the summer, DS will be 22 months old at the time. We currently have a besafe izi combi x 3 isofix for use in UK, but think this is far too big and heavy to take on a plane....what do others do when they are going abroad? If we were to buy a 2nd seat-any recommendations? We are flying and then would need to hire a car for some short journeys ( up to an hour). The country we're going to does not seem to have strict laws about car seats and so we wouldn't be happy to hire one over there. Any suggestions appreciated. Thanks
