As a neuroscientist who has spent her career researching sleep, Polly Moore never expected to have trouble getting a baby to nap.
But when her first child was born, Moore says, she felt as helpless as any other parent whose baby won't sleep. Although some parents urged her to put her daughter on a schedule, others told horror stories of failed nap schedules.
Then, when her daughter Maddie was 3 1/2 months old, Moore noticed a pattern. Maddie, now 10, seemed to become sleepy about 90 minutes after waking up each day. That reminded Moore of a 90-minute biological clock called the basic rest and activity cycle, which governs wakefulness throughout the day.
