Listening to the baby's heartbeat

Anyone else obsessed with listening to their babies heartbeat on their home Doppler? I'm 13+3 weeks now and a first time mum-to-be and I only heard my babies heartbeat for the first time just over a week ago but my partner keeps telling me I'm crazy for trying to listen to it everyday and hates me prodding my belly with it. I just love hearing my babies little heart beating away, is that such a crazy thing?? 😕😕
