The researchers conducted a scoping review across 18 international studies to determine the experiences, roles, and needs of fathers of breastfed infants and how health care providers can use this knowledge to assist, support, and engage fathers. Examining studies that involved fathers in the United Kingdom, North America, Australia, Pakistan, Jordan, and Taiwan, the review found that fathers of children who are breastfed may feel excluded, inadequate, and helpless. To help these fathers, antenatal support and education should be tailored their needs, experiences, and perceptions. Fathers must be recognized as “fundamental members of the breastfeeding triad” and be engaged from the beginning to promote long-term involvement in their children’s nutrition.
