The first hour, and skin to skin
One of the best-supported things in this entire tool.
Across 69 randomized trials and more than 7,000 mother-infant pairs, immediate or early skin-to-skin contact improved breastfeeding, newborn blood sugar, temperature, breathing and heart rate stability, and reduced crying. The reviewers now advise against running further trials in which the control group does not receive skin-to-skin, on the grounds that the evidence is sufficient.
In the earlier version of the same review, breastfeeding at one to four months was more likely with skin-to-skin (odds ratio 1.82), and crying duration was shorter.
Weighing, measuring, vitamin K, eye ointment and the newborn examination can all wait. Delaying the first bath by more than six hours was associated with more exclusive breastfeeding at discharge (odds ratio 1.20, about 44 more babies per 1,000) and less hypothermia (10% against 17%).
