Have a friend. Her second child always slept through the night and was a very heavy sleeper. That’s it. One kid of every single one I’ve ever heard of. The rest…literal shit show.
Both my kids were (and still are) sleeping 12hrs a night from a few months old, nothing wakes my oldest (currently 4), youngest (1) is a lighter sleeper early in the morning, but will sleep through quite a lot between 1900 and about 0400.
