Oh my gosh. I can remember JUST how that feels. Soon, he will be old enough to find the paci himself and it won't be a problem. We used to have five or 6 in the crib.....ridiculous, but better than getting up all night. In the meantime, just focus on the Ferber. They say 6 months is the time to do it. I have three pre-school aged boys and I didn't know about it until the 2nd baby, which I did at 6 months. It didn't work until 2 months later. The third, however, probably could have done it sooner, but 6 months worked well and after only a few nights. The time I knew I could try was when they slept a very long period (maybe 8 hours) on their own. I always said to myself, if you did it once, you can do it again, and again and again.
So, I think you should keep the paci for a while, certainly at least until he's able to sleep through the night well (a couple of months). Then it's your choice. Mine all had theirs until they were 1, but the experts say they lose the "need" to suck at 6 months, so you're right there. It was just so beneficial to me for certain situations that I hated to lose it, but those were MY issues, not the baby's. Best of luck. I'd love to hear how it goes for you.
