There's some insight into a question that all parents ask: When do newborns start sleeping through the night?

Researchers found that the most rapid increase in uninterrupted sleep occurred between the first one and four months of a child's life.

By five months of age, half of the babies studied were sleeping from 10 p.m. until 6 a.m.

But parents beware; researchers found one in five babies still do not sleep through the night after 12 months.

The study was conducted by the University of Canterbury in New Zealand.
