Inherited beliefs about infant vomiting

The mothers said that the vomiting of the newborn is the livelihood of the father.
They believed that the more vomiting a newborn child had, the more the baby’s skin would become white and clear.
They also believed that vomiting was more than enough milk for the child, meaning that he was getting enough from the mother’s milk.
They also believed that a girl’s vomiting was not intimidating, but a boy’s vomiting was cause for concern.
