hi all- sorry if this doesn't belong here but I couldn't think of where else to post my question! We are traveling to Miami in August and driving up to WDW - just wanted to check what the actual guidelines is for children and restraints in cars... my dd is 7 and currently 131cm tall. St home in the U.K. She still needs a high backed booster seat until she is 135cm or aged 12. I think I read online that children should be in a car seat until 5? She is comfortable in a seat with seatbelt (doesn't go over her face etc..correct position) I just wanted to check the law there!! Thanks in advance!
