I found out, within 5 minutes, that we have been exposed to both MRSA and pneumonia!  Dr. Cook is in contact with disease control to decide if we need to do anything special for Lydia preventively.  I was exposed to MRSA by my sweet grandmother.  So she needs lots of prayers.  We are not sure where in the world Sally contracted pneumonia.  She did not return to the house after finding out to keep Lydia from anymore exposure.
