Conducted research which compared the behaviours of primary caretaker mothers with primary and secondary caretaker fathers. Face-to-face interactions were analysed from video footage with infants at 4 months of age. Overall, it was observed that fathers engaged more in game playing and held their infants less. However, primary caretaker fathers engaged in significantly more smiling, imitative grimaces, and imitative vocalizations than did secondary caretaker fathers and these were comparable with mothers' behaviour
