Our daughter's schedule is like this.

Around 9pm, she gets sleepy and fussy so I breastfeed her so she has some food for the night and she is out cold 30 minutes after feeding. I transfer her over to her crib where she sleeps til about midnight (if not sooner) and wakes up wailing until I get her on the boob.

I'm sure putting her right on the boob is going to (and has) conditioned her to expect the boob as soon as she stirs from any little sleep mode she's been in, so we try and pick her up and rock her to sleep with singing. This does work maybe 1 in 10 times and she'll be out again for another hour or two, but for the most part, she will get exponentially more hysterical if she isn't put to the boob.

I'm pretty sure she is waking up at night missing the breast and so she cries till she gets it. She doesn't seem to be hungry as she will suck for a minute and fall back to sleep. If we put her down before she is fully asleep, she will immediately wake and cry.

She's never had a period where she slept through the whole night like some lucky folks. I've read about getting the baby to sleep on her own, but we never were able to figure out how to do that. We have always had the problem of her getting hysterical if not on the breast so it has gradually gotten to this point of her waking very frequently at night.

We have changed her sleeping habits and she does not take naps in the afternoon, though she does sleep in the morning with multiple short naps, until about noon, which seems to be due to sleeping less at night.

And just a heads up, we don't believe in the "cry-it-out" methods. I expect her to have a good amount of crying when we are changing her sleeping habits, of course, just not leaving her there to cry it out on her own.

Any advice and help is greatly appreciated!

TLDR: Our daughter won't sleep at night and seems to be addicted to the breast. How do we get her to sleep the whole night?
