Your baby’s heartbeat: when it starts and what is normal
When the heart begins to beat, what a normal rate looks like week by week, and why midwives prefer movement over home dopplers.
Baby Heartbeat Monitor: Bubbi
Hear your baby for the first time.
Rest your phone on your belly, put your headphones in, and listen. Bubbi records the moment as a waveform you can keep, save it next to your diary entries, and send it to your partner in one tap.
Bubbi is a keepsake app, not a medical device. It cannot assess your baby’s wellbeing and does not replace antenatal care — if you are worried about movements or anything else, contact your midwife or maternity unit straight away.
