I don't think you can feel the baby's heartbeat, but you can feel their movements and hiccup's. You can hear the heartbeat with a stethoscope.
No, you would have to be a rare case of super-sensitive to be able to feel that. To date, I have never heard of a woman who can feel the baby's heartbeat. What you may be feeling is your own...
No. You can neither hear (unless at a ultrasound) or feel it.
You cant...but you will feel the baby move around after eventually
it can be felt, but not all women feel it... some mistake their own heartbeat for the baby's...
