I am so sorry for this family and will send prayers up for them.
It does seem as if some people have more than their fair share of heartbreak, and often they are very special people indeed. My cousin and her husband is just such a family. They have endured multiple miscarriages, one premature stillbirth at 6 months, a healthy baby girl, then another premature baby at 6 months that lived on 6 hours. Then they adopted and their baby boy was diagnosed with a very rare and very aggressive form of leukemia. They did a bone marrow transplant and he had every side affect from the meds possible in the most severe form. He slipped into a coma the doctors warned he would not survive the night many times. Then they said if he survived, he would have severe brain damage. Today Alex is a gorgeous 4 year old boy, who still goes to have his blood checked every 6 months and is tiny and still catching up, BUT, he is a normal, smart, beautiful little boy!! Miracles do happen and this was definitely one of them and I will pray for one for this family!!
