DS is one this month and still in his rear facing car seat. Cos we live in the Middle East and are moving back to the uk in September we did not want to buy the car seat til we got back to make travelling back easier (we also have to fly back mid summer for a family wedding for 10 days). Can we keep using the rear facing seat here and then get the forward one for when we are back in the summer...does anyone know if this is ok??
