Seriously . . . again?

I think Alaina is just prone to hematomas!  Caitlin NEVER had one of these.  Now this is Alaina's second in a few months.  I left her on the bed while I got Caitlin some paper to do her homework.  She tried to get off the bed and hit my bedside table and scraped her chin.  I soothed her and put her back on the floor and went back to get the paper.  Then she followed me and started climbing up on my chair to get to my desk.  Crash again - I threw the paper at Caitlin so she could get started and soothed Alaina again.  It was several minutes before I realized the bump.  DANG!!
