Did you start out with little t-shirts?
I've never had that problem with any of mine - ever, outside of the bows. I guess you're just lucky.
I agree to stick with t-shirts for awhile. Do you have small little bands that you can put in her hair right now or do your bows have the bands attached?
I started mine out with bands and clipped in barrettes by catching just part of the hair in the band. She very seldom could get the barrettes out, but I did watch her closely, so she didn't try to eat it!
The only thing I can suggest is to keep doing it daily and I would think she'd get used to all of this stuff.
