Deborah,

     I keep my business cards in my purse.  Whenever I see a pregnant mom (I
always have to be positive about this!!!), I hand her my card and politely
say, "When the baby arrives, please feel free to call me if you need to..."
 Most of the time I get very positive responses.  Sometimes I get questions
right then and there.  I have never had my card tossed back at me!
