The baby nursing from its own mother is the most common way of obtaining breast milk, but the milk can be pumped and then fed by baby bottle, cup and/or spoon, supplementation drip system, or nasogastric tube. In preterm children who do not have the ability to suck during their early days of life, the use of cups to feed expressed milk and other supplements is reported to result in better breastfeeding extent and duration subsequently than bottles and tubes . Breast milk can be supplied by a woman other than the baby's mother, either via donated pumped milk (generally from a milk bank or via informal milk donation), or when a woman nurses a child other than her own at her breast, a practice known as wetnursing.
