hi i have a daihatsu sirion 2001- already have a 4 year old in a maxi cosi booster high back seat and currently 10.5month old is in a maxi cosi with easy base.he is big 91st centile height and weight but i am trying to keep him rear facing as long as safe. ideally id like another rear facer but our car is small-ive tried to look online but get nowhere-i live in whitby and there are no stores near me--i do have my older sons maxi cosi ? stage 1 seat which i could use? what would be safest? i really dont think a rear faer would fit expecially as my partner is 6ft4 and sits in passenger seat etc. so which forward facer is safest available? and which rear facer might fit a small car?
