Every little girl needs dress up clothes! My girls never seemed to have enough play clothes. I used to scan garage sales and the occasional thrift shop for dress up clothes. OK, you can't really do that from your hospital room though can you? Bad idea, for now. For later though... high heel shoes, gloves, hats, dresses, those old 50's - 70's era pinifore gown cover ups. Like what Lucy wore on I Love Lucy. Nitegowns., and aprons, again, the old fancy ones.
OK, for now, what to do? Do you let your daughter dress up for Halloween? What's she going to be this year? Time to start thinking about that. Look on-line for costume ideas. I always made home-made costumes for my girls. You can make no-sew costumes these days. Again, I know, you can't get out to do the shopping for it but you can scan online for ideas. If you find something you like and know what you want, get a friend to go buy the stuff you need and bring it to you so you can start working on it in the hospital. If you sew, have them bring in a machine.
Last year when Anna was admitted I was in the middle of making a Cinderella gown for my niece. I took everything with me except the sewing machine (I had to fly to NE, Anna was away in college) and borrowed a machine from one of her friends moms and finished my project right there in the hospital room.
That's about my only idea. You could have someone bring you one of those learn to... kits if you ever wanted to learn how to crochet or knit, if you don't know how already.
Hope you get sprung soon. When you're not feeling sick is the hardest time not to be bored to death. My girls are the same way.
