We've been having a similar problem with our almost 14 month old. We used to be able to bottle and rock her to sleep, but now she won't have it! She squirms and fights. I am certainly not claiming to have the answer...but this is what seems to be working for us. First, I tried letting her do the "cry it out" with checks at 5 min. etc. just for one night and it took a week for her to get over it. She was so upset and ended up terrified if I even tried to take 2 steps from her crib. It did more harm than good for her. It just doesn't work for her...she gets herself worked up and sick.
So, now...what I've been doing...she gets her bath, bottle (yes, we're working on letting that go), then her book and cuddles in her rocker, and when she starts squirming, I ask her if she wants her bed...she usually nods. I put her in her bed with her bink (and one for her hand) and her "puppy", rub her back a minute and say "goodnight, I love you", and walk out quietly. She starts crying and then will stand up...I go right in, help her lie down, and tell her "goonight, I love you"...over and over and over. It started out taking about 10-15 times before she'd just stay lying down and whimper a bit and fall asleep. Last night it was only 1 time...and we even had a nap or 2 that I didn't have to go back in! A couple times I've even gone back in and she lays back down by herself and I just rub her back a minute. So it seems to be working. I do the same thing for naps and if she wakes at night. It's harder at 3am, but I'm trying to stay consistent. I feel the need to respond to her...I can't let her cry and cry and feel helpless and hopeless that I won't come in. Good luck and let me know if you have any other tips that seem to work! I'm all ears!
And to tell you the truth, I just realized when I just put her down for her nap...I already miss rocking her to sleep...and just having her sleeping on my chest and feeling her breathe...I guess I want her to stay a baby a little longer...
