THIS MOM NEEDS HELP 😔

I am a first time mom located in Philadelphia, PA. My son is now two weeks old. I am searching high and low for a children's hospital who specializes in bone deficiency, deformity, or joint and muscle. My son is missing his tibia bone in his right leg. CHOP hospital told me pretty much there is nothing they can do and suggested amputation for my son 😢. This is my first child and I just gave birth to him so the last thing I want to do is amputate his leg. I have an upcoming appointment elsewhere also an appointment in Florida. I will travel the world to find a second opinion and make sure my son has the best care. Please help me find other hospitals that might be able to help my son.
