why may some people disagree that the father should not be the primary caregiver?
- stereotypes = being too sensitive and caring are associated with femininity + in the past men weren't offered paternity leave so mothers responsibility to look after the baby
- biological factors = women have higher levels of oestrogen which is associated with caring behaviours - males may therefore struggle with attachments and detecting infant distress (Hardy 1999) due to low levels of this hormone
- fathers are playmates not caregivers - Geiger 1996
