(WTNH) — A good night’s rest is great for babies and parents, and is crucial for physical and mental development. Infants, ages four to eleven months, get an average of 12 to 15 hours of sleep per day. But what happens if a baby isn’t sleeping that long?
Researchers from Saint Joseph’s University in Philadelphia analyzed data from a sleep tracking app from over 800 babies ages one day to 36 months.
They gathered data from nearly 157,000 sleep sessions over a 19-month period. Scientists found that most babies had an erratic sleep pattern for the first five months. After the babies were five months old, they started showing more predictable sleep patterns.
The researchers also found that the amount the babies slept varied greatly along with their bedtimes. Some babies slept for as little as six hours at night, while others slept for 15 hours. They found for every hour later babies were put down to bed, they got 30 minutes less sleep. So parents, putting your child to bed earlier may help them to sleep more.
Experts suggest that a baby’s bedtime should be between 7:00 p.m. and 8:00 p.m., as the earlier they go to bed, the better they sleep.
