Can skin-on-skin contact help with breastfeeding?

Yes. Absolutely! it's one of the best things to do with a newborn to help with milk supply. The more time mom and baby spend together, the more opportunities to feed and therefore increase milk production. Plus, there are other benefits as well, like temperature regulation and the development of a sense of safety and security.
Yes. Being skin to skin with your baby helps regulate baby's heart rate and temperature, encourages baby to feed more often, stimulates your milk production, and is just a nice way to love and hold your baby. So cozy in skin to skin, and when your little one starts inching his way down to your breast guide him to a breastfeeding hold that's comfortable for both of you.
