More to do with play and stimulation than emotional development
Fathers have the potential to be more emotion-focused primary attachment figures but perhaps can only express this when in the role of primary caregiver
It's tricky to define the father's role in attachment due to differing views on whether they serve as primary or secondary figures, leading to confusion in their role.
Conflicting evidence
Research on fathers' roles varies. Grossmann et al. suggest fathers are crucial, but children develop similarly in single-mother and lesbian-parent families, questioning fathers' distinctiveness.
Counterpoint
Fathers in two-parent families often have unique roles, but single-mother and lesbian-parent families adapt to fill these roles, showing families can adapt without fathers.
Real world application
Research on fathers' roles reassures parents. It shows fathers can be primary caregivers and that single-mother and lesbian-parent families aren't disadvantaged. This reduces parental anxiety.
