Have you read about other sleep training methods? Read The Baby Whisperer or The No Cry Sleep Solution, or Good Night Sleep Tight. That might work better for your boys. Training is always going to be tricky with two!
My understanding with these methods is that you have to go in their room multiple times. Unfortunately, every time I do that if my other child is sleeping, he wakes right up. We are extremely consistent with our bed time routine, pretty sure that we are hitting their sleep window on the head.
I guess I was just curious to see if anyone who did try to take the paci away, just had to give up and let their LO have it again. It seems like since taking it away, things have gotten worse, instead of it being rough for just a "few nights" like I have seen people talk about.
