I live in London and take a lot of taxis and Ubers, as I don’t drive. I’d therefore like to get a car seat that can be strapped in using a seatbelt only, and am looking at a Bugaboo Turtle, partly because it will clip onto the Bee 5 pram. I’m just a bit concerned about safety though - as presumably Isofix is safer for the baby than using just a seatbelt. What are your thoughts?
