Sleeping “through the night”

Posted at 11:12 AM, Apr. 17, 2005

You have probably heard that babies should start "sleeping through the night" at about two to four months of age. What you must understand is that, for a new baby, a five-hour stretch is a full night. Many (but nowhere near all) babies at this age can sleep uninterrupted from midnight to 5 a.m. (Not that they always do.) A far cry from what you may have thought "sleeping through the night" meant!

What's more, while the scientific definition of “sleeping through the night” is five hours, most of us wouldn’t consider that anywhere near a full night’s sleep for ourselves. Also, some of these sleep-through-the-nighters will suddenly begin waking more frequently, and it’s often a full year or even two until your little one will settle into a mature, all-night, every night sleep pattern.
