DH and I are looking to go to Disneyland Paris with our 3 children who will be 3,2&1 at the time of travel. We've never flown with children before and while we know our youngest will be sat on my lap due to her age, everything we read says that the 3&2 year old will have their own seats, but they just seem too young to me to be sat with just a lap belt 🫣 can anyone that has traveled with kids this age give me any reassurance?
