I read a few posts on here about the Sonoline B Doppler so I convinced my husband as he wasn't keen on the idea and as soon as I put it to my belly I picked up the heartbeat right away ☺️☺️☺️☺️ Baby is slightly to the left hand side a low down. Such an amazing sound and felt so relieved!  Would recommend if you get one to go onto YouTube and watch some videos so you get to know the sounds of your heartbeat vs. Baby's heartbeat!
