I keep reading in many posts that babies learn to sleep at night form 0-3 months and how to sleep in the day from 3-6 months. But, I'm curious where this comes from, ie/ where I can read more about this. I said it to DH once and he asked what made me think that, I mentioned that I read it on here. So, of course he asked what made all of the BWs think this....just cause he's that type of person....
But then I got curious, too, and after hours and hours of googling and researching anything and everything about baby sleep habits and development and the like, I can't find anything anywhere at all that says this, except posts in the forum.
I'm not saying I don't believe it, but I am actually interested in finding out more about it. Anyone point me in the right direction? Even a page in one of Tracey's books where she says it and I will be happy to read what she has to say about it.
Thanks!
