If Emma has AAI, I know its a big cost but isn't it safer to get surgery? I have been reading that if she falls the wrong way that she could be crippled or even death. I sure woudn't want to read that post if something happens to her, it would be too heartbreaking.
Atlantoaxial instability can lead to cervical spinal cord injury, the symptoms of which include: neck pain; a drunken, staggering gait; paralysis of all four legs; or sudden death.
Keep her safe Olbear! I know you will.
