You are getting some great advice here, so glad there are people who can do so. I'm also very glad you're getting a second opinion. I just don't think you can get everything Layla needs from someone who acts like it's hopeless.
I hope her bladder infection clears up soon, I'm sure it will now she's on antibiotics. And hurray for solid poop!
Still thinking and praying for her every day. It sounds like she is making some progress. Healing never goes as fast as we would like, so patience is the key (I should talk, I really don't have much myself).
