Sounds like you have lots of good soft food ideas. I had mine out about 30 years ago, so I don't remember what I ate, but I do remember that the recovery was pretty easy, so I hope your daughter has the same experience. I didn't know what to expect, so it wasn't bad at all. Only a few years prior to getting my wisdom teeth out, I had my tonsils out and that recovery was horrid, so I was very nervous thinking it would be bad like that, and I was pleasantly surprised.
I'm sure you're going to take good care of her.
