You are such a good mom, encouraging and teaching your bright, strong, happy child in all the right ways, and then this comes along--what a blow! You can withstand it, and so can she. I did a tiny bit of reading up on AFM; the articles I saw all talked about recovery, which can take a year, but does eventually happen, thank goodness. Your fighter who loves to run will be back up on her feet and stronger than ever after this.
Congrats on being a great-auntie!
On co-sleeping: my son and I did before and for years after he was your daughter's age. We both slept better because of it.
Thank you for updating us when you can, in words or pix (love the shot of her sitting up to eat) and please do share the GFM details.
