What is the latest that a heart can start beating in a baby and where can you feel it at to check?
You will not be able to feel the heartbeat yourself at home. The only way is to listen to the heartbeat, either on a traditional ultrasound or a Doppler ultrasound. Usually, you can see/hear the heart beating on a traditional ultrasound by 7 weeks gestation, and can hear it through a Doppler ultrasound between 10-12 weeks. Hearing the heartbeat so early also depends on the mother's weight (amount of fat on the belly) and the position of the uterus (some women's are tipped backwards, making it harder to hear the heartbeat at the earlier stages of pregnancy).
