Back in again

We are back in the hospital again as of yesterday afternoon.  They are running tests to see what is going on inside his little belly.  They have been keeping him on an IV for fluids since he won't drink anything on his own really except for sips here and there.  I only wish they knew what exactly was wrong with him.  The dr. said that if the blood in his stool continues that they are probably going to call in a gastro dr. to get a second opinion.  Anyways, that is all I know.  I wish I knew more.  My poor baby is hurting and I can't do anything except help him go potty.  Josh and I both stayed the night with him and Sadie spent the night with my friend.  Nothing else to say except please keep praying for results so we can know and help him.
