We are on day 10 of operation "get DS to sleep better" (16m, moving from co-sleeping constant feeding no longer than 2hrs sleep at time, usually a lot less to sleeping in cot, no feeding to sleep and no feeds at night).
It's sort of working...ish, but we have this on going discussion .... he thinks that most babies, worldwide, self settle in their own sleep space/area. I do not agree!! If anyone has any knowledge of actual research or data on this (googling didn't come up with anything) I would be so so grateful.
