My misunderstanding was about the purpose of the steroid. They think the drug will help her lungs further develop and improve, but it's not also intended to directly heal the Chylo. After less than 24 hours she showed a very encouraging response to the steroids. They said that it's possible that removing the stress on her body of having respiratory difficulty could allow her body to use that energy to resolve the Chylo. So it could be an indirect benefit. There is not research stating that's been a direct healer of Chylo, but it could give her the upper hand in healing. Hopefully in a few days she'll be able to graduate to the CPAP which means no annoying tube down her throat.
To Dr. Ahmad, and all her doctors: Thank you so much for everything you do for our little one. You guys are truly amazing and we really appreciate you guys!
