Which statement best describes how sleep patterns typically change from infancy to older adulthood?

• A. Infants sleep many hours with frequent awakenings; children gain more consolidated nighttime sleep; adolescents shift to later bedtimes; older adults experience lighter sleep with more awakenings
• B. Infants sleep little and remain awake; children sleep through nights; adolescents stay asleep all night; older adults sleep deeply with fewer awakenings
• C. Infants experience a sleep pattern similar to adults; children need less sleep than before; adolescents maintain early bedtimes; older adults sleep the same as young adults
• D. Infants require long awake periods; children never consolidate night sleep; adolescents have earlier bedtimes; older adults sleep the same as infants

Answer: (A)

Sleep patterns shift in a typical sequence from infancy to older adulthood: babies sleep a lot, but their sleep is fragmented with many awakenings; as children grow, nighttime sleep becomes more consolidated; during adolescence, bedtimes shift later due to biological changes, while mornings can be difficult to wake up; in older adulthood, sleep tends to be lighter and more fragmented with more awakenings. This aligns with the described pattern of infants having long total sleep with frequent awakenings, followed by increasing consolidation in childhood, later bedtimes in adolescence, and lighter, more interrupted sleep in older adults. The other descriptions misstate how much infants sleep, how sleep consolidates, how adolescent sleep timing shifts, or how sleep changes in later life.
