‘婴育’ (yīng yù) is a formal, compound noun meaning 'infant care'—the comprehensive physical, emotional, and developmental support provided to babies from birth through the first year of life. The character 婴 (yīng) means 'infant' or 'baby', while 育 (yù) means 'to raise', 'to nurture', or 'to rear'. Together, they emphasize the active, intentional process of nurturing an infant’s growth—not just feeding or diapering, but also bonding, stimulation, health monitoring, and responsive caregiving.

This term appears frequently in medical, public health, and parenting contexts—for example, in hospital departments, government policy documents, or parenting education materials. It is more technical and professional than everyday phrases like 照顾宝宝 (zhàogù bǎobao, 'taking care of a baby') and is rarely used in casual speech. While it may occasionally appear in headlines or official guidelines about early childhood development, it is not typically used to refer to animal care, despite the presence of 婴 (which strictly denotes human infants).
