If your LO sleeps through the night, did they do this on their own or did you take active steps to get them to do it?

With LO1, I think he did it on his own, although I can't remember at what age or even for sure that we didn't do anything.

LO2 is 11 months and has recently gone back to 2 wake-ups a night, from 1. We have spent a few weeks working on dropping one of the wake-ups with little success. I can't decide if we should take a break from trying to drop the second wake-up and wait for her to outgrow it, or stick with it.
