No News=Good News?

Yesterday Matthew had his echo cardiogram, but we still haven't heard from the cardiologist. Though we haven't heard the official results, the tech did say that if there was something of concern, she wouldn't have let us leave.  And since we left, I guess no news is good news right now.  As well, yesterday was a pretty good day for Matthew, only sleeping 16 hours instead of the 18 he has been sleeping lately.  And he took twice as much liquid as he has been.  We know one day doesn't mean all is well, but hopeful it is the beginning of a good stretch.
