Millennials were raised by Boomers and Gen X. The Millennials born in the 80s have almost only Boomer parents. It's different for Millennials born in the early 90s.
Oh, and don't forget the teachers at school. As Millennial all my teachers were from the Boomer generation.
You missed Gen X. Unless you're saying Gen X offloaded their kids onto their parents. I can largely agree with that.
It isn't a strict timeline.
