I didn't vote, cause honestly I don't know what to put as an answer LOL! I also have a 5 month old that is doing what yours is doing, the every hour thing, and it is killing me as well. My DD also was terrible at napping. I really feel that babies NEED to sleep more than the tiny 30 min naps a couple times a day she would take. She really looked tired, but just seemed to not be able to stay asleep very well.
For the first 3 months, by DD was sleeping awesome. Unbelievable really. By 6 weeks she was sleeping at least a hour stretch at night, sometimes 8 or more! I have never had a bf baby do this for me. It was so awesome. Well that ended at 3 months, and now we are enjoying the every hour wakeup. In our situation though, she doesn't want to nurse every hour, she is just fussy. She pushes the breast away, and really isn't awake.
I tried the NCSS. It has helped us to be able to get her down for naps easier, and helped for me to get her to stay asleep longer than 30 min. It HASN'T helped her sleep longer at night though, or been a magic cure-all. I am just guessing that it will come with time. (I hope anyways LOL)
