Strength) Real-world application
Research into the role of the father can be used to offer advice to parents as it shows that fathers are capable of becoming primary attachment figures. Also, lesbian households can be informed that not having a father around does not affect a child's development.
Limitation) Research into the role of the father produced inconsistent findings. Some studies suggest fathers play a distinct role focused on play and stimulation (Grossman). However, other studies show that they can be a primary caregiver and adopt nurturing behaviours. Suggests the the role depends more on responsibility rather then gender.
