Is it possible to see baby's footprint through pregnant belly
No, it is not possible. The popular photo of a baby's footprint showing on the mother's belly was photo-shopped. The owner of the photograph has confirmed that is was photo-shopped.
It is possible to see bulges in your belly or see your belly moving around. You can not see an actually footprint because there is uterus, abdominal muscles, fat, and skin in between the baby and the outside of your belly.
