Just agreeing with all the PPs here. My dd never had much interest in the pacifier, so I didn't use it. Do what works for you. If your aunts think it's weird, that just means that your experience is different from theirs. We have a lot more breastfeeding info now than in previous generations, and they may not be up on it. They might not realize how much healthier the breast milk is, how it provides nutrition and immunological benefits, as well as mommy snuggle time -- none of which pacifiers provide. And yes, as babies get older, especially when they start solids, they will gradually nurse less. (Unless they're having a growth spurt, or fighting off germs, or just need more mommy time. There's an ebb and flow there.) They don't nurse 24/7 forever.
I had a hard time learning the baby-wearing stuff. If you're in the same boat, you might want to check out any baby-wearing groups in your area. You can check online or ask around at La Leche League or any attachment parenting groups you're a part of. I think Dr. Sears' Baby Book has some info, and I've heard good things about the Tummy 2 Tummy video. You might need to experiment and practice a while before you get the hang of it. Good luck!
