Most Parents Underestimate How Much Sleep Their Child Needs
The National Sleep Foundation just surveyed 1,024 American parents. At every age group, the average parent placed their estimate below the recommended range. The gap is widest for newborns: 78% underestimate by more than 3 hours.

How Much Sleep Children Need vs. How Much Parents Think They Need
The shaded band shows the NSF-recommended sleep range for each age group. Dots show the average parent estimate. Red annotations show what percentage of parents underestimate. N=977 parents with children ages 0–13.
Note: NSF recommended ranges from Hirshkowitz et al. (2015). Parent estimates are mean values from caregiver reports. "Underestimate" = parent estimate falls below the lower bound of the recommended range.

If you do not know the target, you cannot aim for it. This is not a criticism of parents. It is a failure of information. Medical organizations have published recommended sleep ranges for decades, but those numbers rarely make it into the conversations parents actually have.
The NSF poll found that parents spend nearly 2 hours per day thinking about their child's sleep. But 49% never or rarely discuss it with anyone else. The knowledge gap is not about caring. It is about isolation.
This graph is the first in a 20-part series walking through 92 graphs from 40+ published studies on children's sleep. What is normal. What varies by culture. What happens at bedtime. What the research says works. And what goes wrong when families do not have the information they need.
