Hi T.,
My son is now 11 months old. For about a 2 week period around when he was 5 months old, he started sleeping through the night, 11 hours a night. Then as quickly as it started, it stopped again. He got in his first teeth around that time so I attributed it to teething. Over the next 4 months or so, I kept blaming it on teething or that he was sick or anything that I could possibly blame it on so that I could justify why I was getting up to soothe him so many times a night.
By the time we went to the doctor for his 9 month appointment, he was waking every couple of hours and I couldn't remember the last time I he had slept for 6 hours straight. I asked the doctor for his advice and he asked about his going to bed routine. I told him I fed him then rocked him to sleep. The doctor told me that it was MY fault the baby wasn't sleeping through the night because I was rocking him to sleep and every time he woke up, he expected me to come back in and rock him to sleep again, which I did. He told me that I needed to start letting him put himself to sleep, basically to follow the Ferber method.
In the back of my head, I knew all of that, but I was doing everything to avoid having to let my baby cry. But I didn't know what to do anymore, so my husband and I decided we had to at least try it. The first night was horrible, the baby cried for 5 hours straight and then only slept for 2 hours and was up again for the day. Over the next few nights it got better as far as length of time crying, but the baby would start vomiting as soon as I put him in the bed. So we would change him and his bedding and start over. He vomited for about 5 nights straight. After about a week and a half, he was going to sleep within 5 minutes and sleeping for 11 hours a night. He still has a bad night here or there when it takes him a hour or so to fall asleep, and once in a while he wakes up in the middle of the night too, but we just go in there and rub his back and he falls back asleep--we don't have to take him out of the crib and rock him anymore.
I'm not going to lie, the whole process was brutal and I wept every night and drank a lot of alcohol. But he is sleeping so much better now, he is getting over his illnesses quicker because he sleeps better, and my husband and I are much happier because we get a whole lot more uninterrupted sleep.
There is also a book called the No-Cry Sleep Solution if you are really against any cry it out method. My friend is trying this and it is slowly working over time. Whatever you decide, good luck to you!
