The meds that MckMama are taking to keep Stellan's heart working are making her very sick now. She has been admitted to the hospital and taken off of the drug as it is upsetting her own heart. If Stellan doesn't do well without Mama taking the drugs, they will have to take him a bit early. Every day he can spend inutero the better, of course.
I don't know these people personally, but have been following her blog for quite a while. Please pray for their family, the doctors, MckMama and Stellan. They could use it. If you want, grab her button for your own blog so others will see and maybe feel led to pray also.
