Hmmm well I can answer that I would probably not count that deep breath as a break in the cry...but I also think here, just use your judgement. If you think that it would be better to wait a bit longer than do so, but the general advice is we are talking less than a minute, IYKWIM. Once Cate began to get the idea here, I would wait a bit longer and longer. Also, I would use my voice..."momma's right in the hall if you need me, I'll always come if you call me, etc."
Oh, let me say, that since my dd NEVER fell asleep on her own before I started this, I believe that I actually did the thing where I had a chair in her room and I moved it closer to the door each day or two. Then I started WI/WO....sorry, I completely forgot that until just now. When I did that, I'd tell her mommy's just going to sit by the door, in the hall, etc. Then we got rid of the chair completely.
I don't know the answer about the morning feed. My gut tells me, give him breakfast at the proper time. And a nap at the normal time. It was hard for us to keep her up when we went through that, but I'd do anything I could to keep her up.
BUT the warning here is my dd did not stop waking early until I forced her to wait until a bit later in the a.m. to have her nap (the BW books or boards say that because the baby might realize that they can nap not long after waking i the morning, they will keep waking early (or something along those lines). It was true for us.
