When do babies sleep 7pm to 7am?

My cousin's baby started sleeping through the night around 6 months, but 7pm to 7am is a bit ambitious, I think. Most parents I know are happy with 5-6 hours straight. Every baby is different, yaar.

Wow, 7pm to 7am sounds amazing! Does that really happen for all babies eventually? How old are they usually when they start doing such long stretches? And what do parents do to help them sleep so well?

Getting a baby to sleep 7 to 7 is about consistency and routine. Just like we train our bodies for fitness, babies respond to a predictable schedule. Make sure they get enough active awake time during the day too, that helps them sleep better at night.

That's the ultimate goal! It varies, but usually not before 6 months, and often much later.
