@godshapedhole Yes, I think the reason is many parents feel they can't get anything done with the baby in tow. And for many it's true! Babies are gonna baby.
Personally, I don't think the solution is obsessing over a 2.5. vs 2.75 hour wake window and having to put baby down in a pitch dark room at set intervals during the day. How would I ever be able to go out, do anything, enjoy our day?
This man's kids are older but he claimed he did that when they were a few weeks old. Under 2 months I think. He also suggested the same CIO method to a new dad who had a
4 days old (!!!) baby who was obviously clusterfeeding.
I had such a visceral response to the thought of CIO with newborns... maybe his kids had low support needs for sleep and went to sleep just fine, I don't know - babies have different temperaments after all. When I can't respond immediately, my child
screams - I mean blood curling screams, tears, choking on her own spit.
