According to the Kingdom Strollers website, the strollers won't work for a child that size: City Elite Double The City Elite Double™ will be sure to turn some heads. The City Elite ™ triumphs in its design and ease of use. The City Elite Double™ has a weight capacity of 100lbs and is good for children up to 50" tall. Mini GT Double NEW for 2012! The City Mini GT™ series is the perfect hybrid of the Mini and Elite. Best suited for children 46" or less (100lb weight limit), the City Mini GT™ combines the compact form of the Mini with the comfort feature BOB Revolution Duallie The BOB Revolution Duallie™ features all the greatness of the single at twice the fun. Its light weight frame makes it easy for mom or dad to steer through any crowded park. The BOB Revolution Duallie™ has a weight capacity of 100lb and is good for children up to 47". If you check the website for those strollers, I'm pretty sure they say each side can hold no more thn 50 pounds. I think if you want a stroller for your older child, you would be better off renting in the park for her. I have seen 8 and 9 yr olds in them - especially one child in a double if it was a larger child. They have made strollers bigger than they were when my kids were little - youngest DD had to get a wheelchair when she was 3 because she couldn't walk and, even though she was small for her age, the strollers just were not made for older than toddlers. They are bigger now than they were, but a 52 inch tall child is just not going to fit in a stroller made for a child much shorter.
