Abstract/Description
The current study examined the effects of kangaroo care on breastfeeding practices, infant stress reactivity, and biobehavioral measures of mother-infant bonding across the first 3 months postpartum. Additionally, the role of breastfeeding in infant cortical maturation in the frontal lobe was examined. Thirty two mother-infant dyads participated in the current study; 16 mother-infant dyads were randomly assigned to the kangaroo care group and 17 mother-infant dyads were assigned to the...

Additionally, the role of breastfeeding in infant cortical maturation in the frontal lobe was examined. Thirty two mother-infant dyads participated in the current study; 16 mother-infant dyads were randomly assigned to the kangaroo care group and 17 mother-infant dyads were assigned to the control group. Mothers in the kangaroo care group received training on proper kangaroo care procedures by a trained administrator during the first 1-2 weeks postpartum. Mothers in the kangaroo care group were asked to use the kangaroo care procedure for 1 hour per day for 6 weeks. Maternal perceptions of fetal attachment, mood, feeding intentions, and urinary oxytocin measurements were assessed prenatally. At a newborn visit, infant neurobehavioral functioning and urinary oxytocin measurements were assessed. Maternal mood and feeding practices were also assessed at the newborn visit. At 3 months postpartum, mother-infant dyads were assessed on urinary oxytocin measurements. Mother-infant dyads were recorded during a play session and feeding session. Infant baseline EEG recordings were taken over a 5 minute period. Infant cortisol measurements were collected from infant saliva before and after a mild behavioral stressor, an infant arm restraint procedure. Maternal perceptions of postpartum bonding, mood, infant temperament, and feeding practices were also assessed. Results indicate that kangaroo care produced medium to large effects on cortisol reactivity, dyadic bonding, and breastfeeding practices if kangaroo care was practiced for the recommended amount of time. Kangaroo care produced medium to large effects on oxytocin levels in motherinfant dyads regardless of use. Cortical measures of infant frontal activity indicated that all infants in the samples displayed functional maturity of the frontal lobe. Kangaroo care can be used a viable, low-cost tactile procedure that can be implemented after birth to aid in breastfeeding practices, mother-infant bonding, and lower infant stress reactivity. Infants in the study who received at least one breastfeeding session displayed advanced patterns of frontal activation. Further study is needed to determine if peripheral oxytocin measurements are 1) reliable and 2) are indicative of dyadic bonding behaviors.

Kangaroo care with full-term infants: maternal behaviors and mother-infant bonding
Title
Kangaroo care with full-term infants: maternal behaviors and mother-infant bonding.

Abstract/Description
Kangaroo care (KC), has been shown to promote healthy development for both pre-term and full-term infants, and to improve mother-infant bonding (Ludington-Hoe, 2011; Charpak et al., 2005). Current research on the maternal benefits of kangaroo care is scarce, primarily focuses on early KC, and is mostly qualitative in nature (Fegran, Helseth, & Fagermoan, 2008; Matos et al., 2010). The present study examined the effect of late KC on maternal behaviors, sensitivity, and mother-infant...

Current research on the maternal benefits of kangaroo care is scarce, primarily focuses on early KC, and is mostly qualitative in nature (Fegran, Helseth, & Fagermoan, 2008; Matos et al., 2010). The present study examined the effect of late KC on maternal behaviors, sensitivity, and mother-infant interactive mutuality when infants were 3 months of age. Mothers who used kangaroo care as directed were found to have greater bonding scores and less anxiety about caring for their infants as measured through the Postpartum Bonding Questionnaire. Kangaroo care was also found to have an effect on mothers’ ability to effectively calm their infants after an arm restraint task. Further research on the usefulness of late intermittent KC with full-term infants is needed.
