We are traveling to both London and Barcelona with our 4 year old. She weighs 42 lb now, from my research she will need a E approved seat with a back to travel legally. We will be traveling in private cars in addition to public transportation. I would prefer we just bring a seat vs renting or buying one when we get there. I can't for the life of me figure out if there is a car seat that is sold in the U.S that is for her weight and is E approved. Anyone have any suggestions? We will travel in late July and if she can reach 48lbs by then I think she can use a backless booster, but I don't think she will gain that much that quickly.. Thanks for any help.
If you can't get a suitable one in the US, you could order it from Amazon.co.uk and have it sent to your London accommodations.
Perhaps you've already read the legal requirements for child car seats in the UK - if not see below
