I hope that sweet little girl will make a good recovery. I took in a little girl who was paralyzed from the waist down upon intake too and the Gabapentin worked miracles for her! She's gained most of her mobility back, but still struggles with her back legs a bit. Here is a link to her thread which contains some videos for reference.

She wasn't quite as young as your little one is, but made such great progress - I will be praying the same for your baby.
