How to get a newborn to sleep through the night?

Nearly all babies are able to sleep through the night by 6 months, but when they do is very different depending on the child.

Some infants as young as 3 months old can snooze for six to eight hours at a stretch. Others won't sleep this long until they're 12 months old. But most babies (70 percent) do sleep through the night by the time they hit 9 months, according to the National Sleep Foundation.

Sleeping through the night usually means sleeping for eight to 12 hours straight without needing a nighttime feeding.

You may have heard that bigger babies and babies who eat solids are better sleepers, but it's not true. Your baby's ability to sleep through the night depends on age, not size or diet.
