A very strong baby
Although a woman feels her baby pushing in the later stages of pregnancy and can even see bumps on her belly, the abdominal walls are too thick for a foot to be seen this clearly. In addition, the foot is too big for an unborn baby. All in all, this little guy would’ve surely been no less than a Hercules, if only he existed. The source of the picture is unknown, but it’s probably made up, just like later copycats.
