I have heard that it is common for fathers to the eat the umbilical cord
Dr Benoist Schaal, researcher at the Dijon-Dresden European Laboratory for Taste and Smell (Centre National de la Recherche Scientifique), states that eating habits start in the womb. He explained a study conducted by himself, along with researchers Luc Marlier and Robert Soussignan, on how unborn babies “learn odours from their pregnant mother’s diet.”
The scientists asked a group of pregnant women to consume anise flavoured cookies. Once they gave birth, researchers tested their kids along with others whose mothers hadn’t consumed the cookies. They found that the former recognized the smell and showed a good disposition towards it, while the latter rejected it.
