From Bergman et al 2004 RCT SSC time first 24 hr correlated with SSC time first month. Infants with skin-to-skin contact began responding to changes in their mothers’ behavior with their affect at 1 month; infants without skin-to-skin contact did so at 2 months. 14 At 3 months, infants with skin-to-skin contact increased their non-distress vocalizations during the still face phase, suggesting social bidding to their mothers. Conclusion: Mother/infant SSC benefits mothers by reducing their depressive symptoms and physiological stress in the postpartum period. JOGNN, 41, 369-382; 2012.

WHAT IS NORMAL FATHER BEHAVIOUR ?? Twelve parents (6 mothers and 6 fathers) Taken by surprise: For mothers, the premature birth created a feeling of powerlessness and they experienced the immediate postnatal period as surreal and strange. Using a modified frequency method, behaviors were identified in four main categories: proximity, gaze, touch, and movement. The analysis showed that proximity and gaze were high-frequency behaviors and touch and movement were low-frequency behaviors. Tomlinson 1991 Taken by surprise: For mothers, the premature birth created a feeling of powerlessness and they experienced the immediate postnatal period as surreal and strange. The fathers experienced the birth as a shock, but were ready to be involved immediately. The fathers experienced the birth as a shock, but were ready to be involved immediately. Fegran 2008 26 Mothers engaged in more caregiving, talking, and holding during initial contacts, but the disparity in maternal and paternal interactions decreased with time. Except for caregiving, in which mothers still surpassed fathers, fathers equaled mothers in all other activities at the time of the infants' discharge from the hospital. Fathers consistently surpassed mothers in playing and stimulating. After C/S 29 father-infant pairs participated either skinto-skin with their father or next to the father in a cot. SSC infants became drowsy within 60 min after birth, infants cared for in a cot reached the same stage after 110 minutes. Levy-Schiff 1989 Infants in the skin-to-skin group cried less than the infants in the cot group (p < 0.001). Results demonstrated that both mothers and fathers rated their experiences of love significantly higher when holding their infants skin to skin than when holding their infants wrapped in blankets (differences two types of holding: mothers p= 0.0002 fathers p= 0.0001 The crying of infants in skin-to-skin group decreased within 15 minutes of being placed skin-to-skin with the father. Gloppestad 1998 We found that We found that (1) fathers hearing the cry stimuli felt more sympathetic and more alert …; (1) fathers hearing the cry stimuli felt more sympathetic and more alert …; (2) fathers and non-fathers with lower testosterone levels had higher sympathy and/or need to respond … ; (3) fathers with higher prolactin levels were also more alert and more positive in response to the cries; (4) fathers hearing the cry stimuli showed greater percentage increase in testosterone …; (5) experienced fathers hearing the cries showed a greater percentage increase in prolactin levels … (6) … both experience and testosterone contributed to the variance in fathers' affective responses to infant cries. Fleming 2002 27 Taken together, these results indicate that, as with a number of other biparental species, human fathers are more responsive to infant cues than are nonfathers and fathers' responses to infant cues are related to both hormones and to caregiving experience Fleming 2002 Maternal OT was related to the amount of affectionate parenting behaviors … … whereas paternal OT correlated with the degree of stimulatory parenting behaviors … DOPAMINE Given the central importance of rewards for survival, reproduction, and competitive gains, it may not be surprising that several specialized and only partly overlapping brain mechanisms have developed during evolution.
