So I dopplered again today lol.
It's longer than I thought I would last without checking hehe.
Anywho... took me only a minute but I found the HB and it sounded just like a little train chugging along.
I remember Zoe's sounding more like galloping. But then again I didn't try with her until 16w so maybe it changes the way it sounds the further along you are?
I did record it, but I put the camera right under my nose so it's a nice video of me breathing right in to the camera mic. DOH... didn't even think of it until right after. Sigh.
I'll try again later... maybe next week if I can start picking it up a little more consistently.
