Have you thought about a child-size sewing machine that just does straight stitching and skip the handwork? You and your daughter both can get many hours of entertainment from sewing simple 4 or 9-patch blocks that you can partially sew into tops (until they become unwieldy for the sewing machine) then finish at home. You can take a kit with the machine, scissors, a seam ripper (yes you'll still need it-lol), thread etc. You can precut the squares or strips and take a small cutting mat and rotary cutter with your travel kit. The small machine will sit on the hospital bed tables. Will be fine if your daughter can be sitting up part-time. If not, you can do the sewing and your daughter can do the block layout on her bed (or directing you on how to place them!).
