I've been trying to find the hb with my doppler for a few days because I found it the first time I tried with DS2, right at 9w0d. So I thought maybe I could find it a few days earlier if I tried. I didn't find it the last couple days, but today I did... A nice, strong 168-169 beats per minute of sheer wonder!! Ahhhh, the best sound a mama can hear, aside from the first cry (and of course, "I love you, mama"). Sooooo happy!
