I have two very good friends.
One has children. She started putting them in the crib in their own room from day 1. One slept through from two or three weeks, the other is three months or so now and wakes up once.
I have two children. The first slept through from about four months (I think....he's seven and a half now and I can't remember back that far!). My DD is 19 months and honestly did not sleep for more than three or four hours and a time no matter what I did til she was almost a year. I started cosleeping with her when she was a few months and that helped somewhat. I just wasn't comfortable leaving her to scream and that is what she would do if left alone. She's been a solid sleeper since about a year; she never sleeps with us anymore. She will occasionally wake in the night (maybe every few weeks) but will settle when given a drink and go back to sleep.
I'm pregnant with #3 now and am just planning to cosleep from the get go. We enjoyed it last time and it worked well. Plus the baby will eventually have to share a room with either DS or DD and it might work best (room arrangement wise) to move the baby when he/she is ready for a big bed.
Plus I do feel that cosleeping is best...in the way that breastfeeding is "best". That is, best if you can/don't mind it but obviously not best if it stresses you out OE you find it awful etc.
Every time this comes up with Friend 1 (the one with kids) she insists that putting her DD in her own room from birth "made" her a good sleeper and that I am making a mistake in not planning to "make" my DC3 a good sleeper.
Friend 2 (without kids but planning on TTC soon) has told me today that she will definitely not be cosleeping because "look at Friend 1, her DD slept right away and I just don't function without sleep.". I told her I don't either and that is why I coslept...it was the only way for us to get any sleep at all!
She clearly didn't believe me and (it's probably hormones) it is irritating the crap out of me. I feel like some babies are just naturally good sleepers and some aren't, no matter their sleeping arrangements.
AIBU? And hormonal? :o
