In some families in Russia, it is not customary to hold large-scale celebrations to mark a new family member arrival. In addition, even if a party is organized, it is only for the closest ones. If you want to visit your friends’ newborn, it is better to postpone this idea for at least a month after the birth, otherwise you may inadvertently transmit serious negative energies to the baby. In Russian, there is a corresponding term: “to jinx / put the evil eye on”.
