Hi there! I feel your desperation, I was just in a similar place about 2 weeks ago. I slipped in accidental parenting. My lo had lots of tummy issues, so we rocked and held him until he fell asleep. It was so hard to get him to sleep. Once he was asleep, and we laid him down he woke up and the whole process started all over again. I am new mom so I dont know if this will be much help, but here is what I did.
1. I bought the miracle blanket.
I realized my son longed to be in the womb and need to be swaddled to feel comforted. The first night he slept from 10:30 to 6:30!
2. I bought a pillow that raised his head a bit and also acted as a wedge.
He loves this. I am not sure if it is the extra padding, helps with reflux, or adds to the swaddled effect.
3. I watched him like a hawk looking for his sleeping cues.
Once I saw one, I started the wind down routine.
The next steps were gradual for us. I took one chunk at time.
4. Started a wind down routine.
For about ten minutes, I would swaddle him, take him in an almost dark room, and whisper lullabyes. I only did this until I felt he was ready for the sleeping routine. Then there is no talking. In the beginging he cried. I just shhh real loud, rocked vigously, and patted. I stopped rocking when he stopped crying, but continued the other 2 things.
5. I rocked, shh, and patted him for a few days until he was asleep or close to it. Then lowered him into the bassinet (sort of tilted on his side to alleviate the falling sensation) and continue shh, patting and maybe rocking the bassinet. I only did this a few days.
6. When I felt that he was liking the shh and patting, I gradually elminated the rocking and just shhh and patted him. The rocking time gradually got smaller.
7. Now I shh and pat until he almost asleep. Then lay him on his side (using the wedge) in the crib and shh and pat. I do this until he is all the way alseep. To be sure I do it for about 10 to 15 minutes after I think he is asleep. This is key to ensure that he stays asleep. It might not seem to work at first, but keep trying it will work.
8. Be consistent! Find the routine that works for you and stick with it. Babies like to know what comes next and love routine.
Also, if your lo wakes up aroud the same time every nap, beat him to it. Start patting and shhh just before the time he usually wakes. I still have to do this becuase my son sometimes wakes after 45 min.
This takes a lot of time at first, but well worth it in the long run. It has been a couple of weeks and now my son knows that when I swaddle him it is time. Dont get me wrong though, things aren't perfect he still cries a little, but it is far better that it used to be. I know it seems as though there is no end in sight, but just keep your chin up it will get better. Get tracy's 2nd book, it is more detailed with her advice.
I am sorry for the chapter book. I hope something helps.
