my 2.75 y/o is right at 1 inch above her head in the MR, I don't want to buy a new seat for her unless I would get alot of growing room out of it, she is quite tall for her age, weighs 36 lbs and wears 4T shirts comfortably, 3T with the sleeves a bit short. I don't know her seated height. Any thoughts on what seats would be tall enough to keep her RFing another 6 months? Also, what would most do, purchase another seat or turn FFing? I already turned her in our secondary car b/c we needed to get the 3 across to work better?
