Oh, the sleep debate.
My first child slept for about 6 hours straight at night from 6 months. I thought that was the longest six months of my life.
My second child started sleeping through from about 2 years.
When the MCHN asked at 12 months, (and, as a fellow overthinker, I remember it well) I told her the truth. And she asked if I was ok with it. And I said I was. It was fine. Not one of 'those' children who sleep through from birth, but it was ok. She asked if I wanted to consider 'options' to get him sleeping through and I said no. I wasn't prepared for sleep training advice. She said if I wasn't coping or wanted advice then I could come back.

Anyway, I just shared because it was kind of the same as you. You aren't alone. I was always feeling protective of him and his need to have comfort at night.

And yes, there are children who actually do sleep though. Even bf ones. My SIL has 3 girls. The newest is not even six months and she sleeps from 6 til 6. No kidding. The mythical 'sleeping through the night child does exist'. Her others didn't though. So maybe one in three is good odds.
