Yes, it’s completely normal! –

Who told you babies sleep through the night by the time they are a year old? Most don’t, a new study finds.

Only 57 percent of babies stay asleep for eight hours straight at the age of one year, Canadian researchers found.

Their study published on Monday also shows that, contrary to common wisdom, a mother’s mood did not depend on babies sleeping through the night. Total sleep, including naps, might be more important than getting eight consecutive hours, they wrote in the journal Pediatrics.

“If there was only one thing I could tell parents, it would be do not worry if your infant does not sleep through the night at six months of age,” Marie-Hélène Pennestri of McGill University, who led the study team, told NBC News.
