What sleep problems are common in toddlers and adolescents, and what daytime effects are associated?

• A. Toddlers: bedtime resistance and night waking; daytime mood changes. Adolescents: delayed sleep phase and difficulty waking; daytime sleepiness and mood changes.
• B. Toddlers and adolescents: identical sleep problems; same daytime effects
• C. Toddlers sleep through the night; adolescents have early morning alertness; no daytime effects
• D. Toddlers: insomnia; adolescents: narcolepsy; daytime effects: hyperactivity

Answer: (A)

Sleep problems vary by age, reflecting how sleep needs and circadian rhythms change as children grow. In toddlers, bedtime resistance and night waking are very common, and these disrupted nights often show up as daytime mood changes, irritability, and lower energy. In adolescents, a delayed sleep phase is typical—the internal clock tends to shift later, so falling asleep at an earlier time becomes hard and waking up for school is challenging. That mismatch leads to daytime sleepiness and mood changes, and can affect attention and behavior during the day. This pattern fits best because it matches how younger children struggle with initiating and maintaining sleep, while teens struggle with aligning their sleep timing to early-morning obligations. The other descriptions either claim the same problems across ages, or propose sleep issues (like narcolepsy or insomnia) that are not characteristic of these developmental stages.
