Button Update, again

It looks like I may have been wrong on two accounts, and the kids right on both.
First was my prediction Button would die within a day or two of being with us. Clearly I was wrong there, and glad to be so.
My second area of wrongness seems to be in what kind of bird our little Button is. The kids kept saying she was a sparrow, but I was insisting she's a robin. Elizabeth found pictures online of baby sparrows which looked like her, and I found pictures of baby robins which also looked like her. To me, her feathers definitely looked black, so I just knew she was a robin. Never mind there was not a single hint of orange in her chest feathers...
Well, now that a little more time has passed and we've had her out in daylight, I'm thinking we have a little sparrow here. Imagine, I've been wrong two times in two weeks. What's happening to me???

Button is flapping her little wings quite a bit now, which has led the kids on some new adventures.
At some time in the past, while watching a TV show on PBS, Joshua saw a segment about raising baby birds and particularly about teaching them how to fly. How convenient! So putting this knowledge to use, the kids have been holding Button in their hands and gently moving her up and down to give her the feeling of flying. Today they ran excitedly into the house, wanting me to come out onto the porch and see Button's flying progress.
Elizabeth held Button then gently tossed her up in the air. Button flapped her wings and made a soft landing. She isn't taking off by herself yet, but she's learning how to land!
When my kids first told me they were going to teach Button how to fly, I thought, How do you - a human - intend to teach that little bird to fly? You can't exactly grow wings and show her how it's done. Ugh, could that be three times I'm wrong now?

Yes, this little bird has been a delightful addition to our family. Tomorrow I'm going to call a wild animal rescue shelter in a nearby city to ask them about releasing her. We're wondering if we can get her ready, or if we should take her to them and let them do the release. It will be sad to see her go, but what good memories we've built with her.
