Has anyone had much luck finding strollers, high chairs, and/or car seats that they can fit into somewhat comfortably? I found a Graco twin stroller a couple of years ago at a yard sale, and fit into it if I fold down the front seat and then sit against the rearmost backrest, but my legs are kind of forced straight out with my feet dangling. I have not found much else that really works for these items. Having safety belts/harnesses with these would be an added bonus. If you have these items, what has worked for you?
