The paternal bond is typically the relationship between a father and his child. In the U.S., legal paternity is presumed for the husband of the mother unless a separate action is taken; an unmarried man may establish paternity by signing a voluntary recognition of paternity or by taking court action. Paternity may also be established between a man and a younger person, commonly in adoption, without the two being related to each other.
Fathers find many ways to bond with their children, such as soothing, consoling, feeding (expressed breast milk, infant formula, or baby food), changing diapers, bathing, dressing, playing, and cuddling. Carrying the infant in a sling or backpack or pushing him or her in a baby transport can build the bond, as can participating in the baby's bedtime routine.
