I don't think I paid very much for my stethescope either! I remember listening when my Lily was pregnant and trying to guess how many she was carrying....I just can't remember how soon I actually heard it. It is amazing to hear their rapid little heatbeats! I really wish that we could just have them pee on a stick to see if they are pregnant...LOL
. It may be too early, but I still listen everyday with my stethescope in hopes of hearing something!
