Urgent Help for Landon's Medical Needs

My name is Brooke, I am raising funds for my Godson, Landon. He has been in Children's hospital for close to a month now, and is not getting better. He is non-verbal autistic, has Cerebral Palsy, and gets his medications and feeds through his GJ tube. He has not been tolerating his feeds well, even after a second surgery, and multiple other evaluations to figure out why. Now, the hospital is talking about sending him to see a specialist, which is not covered by insurance. Thank you!
