For 11 years I worked with a very sweet lady. Her two year old grandson is in St. Jude's fighting a brave fight. His specific issue right now is his oxygen levels. They aren't sure what is causing the levels to not level ou. I'm attaching info from a post made by his mom. As you read it, remember that she was very pregnant when they came to St. Jude's. She delivered while Sam was there, and their baby girl is back home. This family has been through a lot. (He's the little man in my avatar and that Diznn's refers to.) the doctors are going through different possibilities, the worst case is that's it's a disease from the chemo. If thTs the case then discussions will begin about quality of life. I cannot even begin to fathom how a mom of a two year old can even have to consider that. So, please, send up prayers for them all. If you want to follow the family and their story, look on Facebook for Praying for Sam #samstrong. You will fall in love with him, so beware.
