Hi, L.!
First, I am sorry to hear that you've had a rough time lately. Don't put yourself down - babies are hard work even if you're having a lovely year! :-)
My son always nursed to sleep (I know, I wasn't supposed to!) until he randomly weaned himself at 11.5 months and became a "bottle baby" two weeks before most pediatricians will tell you to take the bottle away!! Now, at 14 months, we have learned a few things.
First, we always had a routine (bath, lotion, pajamas, book, nurse and then bed) but if you don't, it really is not too late to start one. We kept the bath, lotion, pajamas and book, so he knew what was coming next. We would then start a CD (a new thing that he loved) and give him the bottle, but if he started falling asleep, we would take it away and put him in his crib.
The first week was NOT so fun because he would scream at being put in his crib while still awake, but babies are SMART and he figured out that as soon as he stopped drinking the bottle, he would be put in his crib. He gradually started making that decision for himself and now most nights he barely drinks the bottle at all and is just ready for bed. He has learned to turn on the CD player and that is a really special task for him and it comforts him. We have started to only offer the bottle every other night and I think we are almost done completely!!
I know this is long, but I hope our little experiments and successes help you. And again, if you get criticism, remember that at some point, the same people who are criticizing you probably had their baby spit up on them in public!! :-)
