I had the same problem and was at my wits end! My daughter is 4 months old and had to be held to go to sleep, would not sleep more than 30 minutes at a time, was cranky, fussy, my back was killing me from holding her or having her in a sling all the time (and I mean literally ALL the time!) I was stuck and didn't know what to do. I wrote to MamaSource myself on March 10 regarding this problem, (you can read my post) but since then things have gotten so much better! Frankly, I didn't have the time (or the inclination) to read a bunch of books and all that, I needed a solution FAST -and just so you know, I am 100% against "crying it out" so if you don't want to go that method, here's what I did.
1. We reintroduced the swaddle. We stopped swaddling her because we thought she was too old, but I noticed that often she would startle herself back awake. So we started doing that again and it was a big help.
2. Then we got a white noise machine online:

It is a cute teddy bear and it works like a charm. We take it to Grandma's house and she sleeps there too! Beware though - many times I have put her down with the intent of "getting things done" while she is napping, but with that white noise machine I often conk out too!
3. For naps I usually lay her down on our bed with the white noise bear and nurse her and she usually drops off in between 5 - 15 minutes. Sometimes we nurse in the rocking chair and then I put her in her crib. She takes 3-4 naps a day for between 45 minutes and 2 1/2 hours. I let her determine how long she needs to nap for. She doesn't stay awake for more than 2 1/2 hours between naps though - as soon as she is yawning and rubbing her eyes, she needs to go down for a nap. Darken the room for naps, when she wakes up from a nap, open the blinds and let the light in so she figures out day and night. Close the blinds before the next nap to make the room dark(er).
4. At night we co-sleep. I nurse her down in our bed around 7 pm, swaddled and with the bear, (then it is our time - my husband and I have dinner, watch a movie, etc.) and we keep an eye on her with a video monitor just in case she wakes up, but she usually doesn't. If she does have a hard time getting to sleep I will go back upstairs and nurse her and comfort her (hold her, sing, hum, rock, whatever it takes) until she drops off and then lay her back down. When we decide we want to go to bed, we turn off the bear and crawl in with her and I usually nurse her again and we all fall asleep. : )
5. Routine routine routine! When you put her down, go through the same steps each time. When she starts showing signs of tiredness, our routine is: Change the diaper, darken the room, turn on the bear, swaddle, lay her down, nurse. This always stays the same. At night we add a story (read to her by Daddy) and a little infant massage on the legs. (We took a class and she really liked it.) When she sees all this happening, she knows it's time to sleep. We are giving her cues and she recognizes them.
So what did we get with all this? We now have a baby that takes 3-4 naps a day and sleeps between 10 and 12 hours a night. It is a miracle! When she is awake she is bright and interested.
And just know this... If you don't want to let your child "cry it out" - You don't have to - there are other methods. If you want to sleep with your baby - You can. The important thing is that you make the right choices for your family. You are the mom and no one knows what is right for you and your family except YOU!
Good Luck!
