Infant care is a research area that focuses on the physical, emotional, and cognitive development of infants from birth to two years of age. Researchers in this field study various aspects of infant care, including nutrition, sleep patterns, cognitive stimulation, social development, and early language development. They also investigate the impact of various caregiving practices, such as breastfeeding, attachment parenting, and the use of childcare services, on infant development. The goal of infant care research is to provide parents, caregivers, and healthcare professionals with evidence-based guidelines for promoting the healthy development of infants.
