No Cry Sleep Solution Method who needs help!

My DS became a horrible sleeper since he was 5 months old and had an ear infection. Since then he will only sleep 1-2 hours at a time, and won't nap unless he's on my lap! Which is difficult since DD is a busy 3 year old. So needless to say we are all sleep deprived and were in need of a sleep solution. So enter "The No Cry Sleep Solution" by Elizabeth Pantley...

I have now been using her method for one month now, and if possible DS is getting WORSE instead of better. What am I doing wrong? I nurse him to sleep and pull him off before he falls right asleep. He usually rolls over and falls asleep the rest of the way on his own now. (Which has improved!). But he still continues to wake up every 1-2 hours! And he's not thirsty; he only actually nurses one time through the night where he actually gets milk, the rest of the time he only nurses for a few seconds, no let-down.

The only time I don't pull him off is after 6 ish in the morning - I put the soother in instead, or else he will wake up. He sleeps in the playpen beside the bed, and I bring him into bed with me after DH goes to work at 5:30.

And he's getting worse! The past couple nights were every 1/2 hour to 1 hour, was restless and difficult to get back to sleep.

I feel like a human pacifier who is literally wearing out. I am tired all the time and feel like it's affecting my parenting. I want nothing better for my kids than to be a great mother for them but find myself getting frustrated. Any suggestions what might help me be more successful with the Sleep Solution? Help!!
