Daughter now 18 months old, live abroad. Returning to UK to visit grandparents whilst husband travels with work. Also looking for solution when visiting friends/holidaying...do we really have to take car seat? (not renting car) Are there no lightweight five-point harnesses available or inflatable chairs? What do you do when going to Barbados, etc. PS: have already lost brand new pushchair courtesy of Heathrow airport, don't fancy losing the carseat as well...and whatever happened to travelling light?!
