I am interested in the affect/health aspects of becoming a stay-at-home dad which for most fathers living in a culture where hegemonic masculinity contradicts this, becomes a liminal and vulnerable state. If attachment theory is based on an interpersonal relationship between infant and caregiver then surely this is a two-way street in the 'motivational and behavioral system'. The attachment possibly provides important resources in terms of emotional support and "safe base" for the father from which to redefine masculinity and to build up self-esteem and reassurance when manliness is being questioned. Any literature on the caregiver perspective in attachment theory?
