How many hours of sleep should 9 yr old girl get? competitive swimmer &martial artist. i have to call her 3 times to get up in the morning for school

Sleep hygiene: Meaning: retiring early, avoiding physical activity at night, TV, computers, smart phones, etc. quiet room. Not waking up easily in the morning reflects sleep deficit, good luck

Depends: A growing 9 yo should get no less than 9 and sometimes as much as 12 hours of sleep per day. The actual need is influenced by mental activity (studying for tests/homework) and physical activity (competitive sports). Falling asleep during sedentary activities like watching TV, car rides, or difficulty rising in the AM suggest a sleep deficit.
