Lauren!
How the heck are ya!!?? WHY did I not know you were in NJ?
Ok.. anyway.. I don't know about one pacifier being better than another, but I did read that you're supposed to wait until breastfeeding is established before offering any artificial nipples.
As far as scheduling, Matthew was all over the place (still is) and would nurse, then nurse 30 minutes later.. then again 3 hrs later.. then an hr later... really scattered. He started to fall into a night time pattern where he'd wake around the same time to nurse when he was around 3 or 4 months. All babies are different, just keep feeding him on demand and he'll be fine.
It's good to 'see' you! Are you on AIM? Terry Lynn and I chat all the time, but I never see any other Spermie Snatchers. BTW did you know TL is due with her 4th on 8/22?
