Infant development during the first year of life is a period of significant growth, encompassing physical changes, cognitive advancements, and language acquisition. Infants experience rapid weight gain, motor skill development, and begin to show cognitive abilities such as learning and memory. Language skills emerge as infants start to babble and eventually speak their first words, reflecting their innate linguistic capabilities.
