Okay, I have a question for you. We may(hopefullly) be taking a young lady with us on our Disney trip in December. She's the size of a 9-10 yr old, spactic quad cp, can't sit by herselft, only her hold her a head up for a few seconds by herself, etc. We have a Columbia car seat that we use for her that works well, and it does have a faa approved sticker on it. Problem is, it's large, and I don't know if I can use it on the plane for her. She'd be uncomfortable, and possiblly unsafe with just the seatbelt on. She goes into extension also, so she'd be sliding down out of the seat to boot. Don't know what airline we're flying yet, but probably one of the big ones due to the airport. Will this be a problem? Any ideas or suggestions would be greatly appreciated.
