Drinking one’s wife’s milk has no effect and does not create the relationship of mahram because the breastfeeding which has an effect is that which consists of five feedings or more within the first two years, before weaning.

There is nothing in the Shari`ah to indicate how often the husband and wife make love because this varies according to circumstances and personal preferences.
