A paternal bond refers to 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 biologically related.
The father of a child can develop the bond during the pregnancy of his partner, feeling attachment to the developing child. Research indicates that this may have some biological basis. Statistics show that fathers' levels of testosterone tend to decline several months before the birth of the child. Since high testosterone levels seem to encourage more aggressive behaviour, low levels may enhance the ability to develop a new relationship bond (i.e. with the child).
Fathers find many ways to strengthen the father-child 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.
