My daughter recently had hip surgery and will be in a spica cast for the next six weeks. She no longer fits her regular car seat, or any other car seat that does not cost $500 or so (and can't be tried out beforehand) -
We spoke for quite a while with the car seat people at the hospital and they basically said that what she needs is a booster or car seat with a high, deep base and no armrests. I've looked everywhere I can think of online and can't find anything that matches that description. In lieu of that she has to use a special vest that makes her lie down in the backseat strapped to the seat belts.
Has anyone heard of a booster or car seat with a high, deep base and no armrests? I've looked the usual places online (amazon.com, walmart.com) with no luck. She is four and a half, 41 lbs and 41 inches tall.
