We were given the 12 Hours by 12 Weeks book for sleep training purposes. We haven't implemented any of it yet because we never met all of the criteria the author "requires" to start the training. We are finally hitting all of the criteria, and would love to try this, but I wonder about how to do it when I have a nanny-share situation with a nanny who feeds on demand.
Has anyone used this technique?
If you have a baby who is STTN, and you work outside of the home during the day, how did you accomplish the sleeping? I see a lot of folks on this board with babies about the same age who seem to be STTN (in some cases they have been doing so for a while now), and so I feel like I am missing something.

Re: Anyone do 12 Hours by 12 Weeks sleep training?
You do know that STTN means a baby is sleeping 6 hours straight. Just making sure bc i am wondering if you have unrealistic expectations.
I'm not expecting 12 hours, although the book does say you can get there. Author adheres to a strict eating schedule during the day, with 2 naps, and an 11-12 hour sleep at night. We have 2 friends whose kids are living proof it works and they swear by it. But the daytime schedule looks fairly strict and I may have a hard time convincing the nanny, who is taking care of another child, to adhere to it.
Right now, we feed around 11:00 p.m. 3:30 a.m. and 7:00 a.m. I just want to eliminate the 3:30 a.m. If the 7:00 turns to something else, that is fine, but the 3:30 is a killer and I would love to get something more than 4 hours between feedings.
While I was pregnant this book was highly recommended to me by another mom. I read it, and it gave me a lot of good "tools" as she calls them, but realistically didn't ever feel up to trying it. My Ds has bee na pretty good sleeper though from the beginning giving me about 6 hours or more starting at around 7 weeks (with some rough nights/patches inbetween).
I think her schedules are really strict though and even though our DC wold abide by any feeding schedule I give them I think feeding on demand is just better now. I will admit the rough nights do occur when DS hasn't eaten a ton while at DC (only 8 or 10 oz vs his typical 13-16). So maybe you can just try getting in an extra feeding during the day instead of implementing a strict schedule and see if that helps first?
