This study will compare standard methods of stabilizing a newborn's temperature after birth with mother-infant skin-to-skin contact for stabilizing newborn temperature. The study will look at the effects of each warming method on the timing of newborns' initial bath and the effects on newborn initiation and percent weight loss by discharge.

The study will use a randomized controlled trial (RCT) design to test a clinical intervention at TriHealth Good Samaritan Hospital. Study participants will be randomized to the intervention group (IG), which will implement mother-baby Skin-to-Skin (STS) immediately after vaginal birth, or to the control group (CG), which will receive standard care for newborn and mother immediately after vaginal birth.

This study will test the hypothesis that mother-baby STS contact implemented immediately after delivery for a minimum of the newborn's first 60 minutes and with a resumption of STS (if a 15-minute break in STS occurs at some point after the first hour) until the newborn's temperature stabilizes after the initial bath will result in:

1. Improved newborn temperature stability and thermoregulation for newborns whether breast or formula-fed.
2. Initiation of effective breastfeeding behavior within 90 minutes of birth and the addition of at least one more breastfeeding within four hours of birth for breastfed newborns.
3. Avoidance of newborn weight loss of 10% or greater.
