For Mavrick, I was lucky because by 8 weeks old her was sleeping 8 hours straight and this while being breastfeed until 4 months. He did have massive sleep regressions though.

For Sienna, started sleeping through the night on christmas eve and has kept the pattern since. That puts her at the 7 month mark.

Crazy how two kids can have completely different sleep.
How long did it take for your LO to sleep through the night (not just 1x)
