Thanks for the responses! Lol, HappyMommy, you and I think/write exactly alike.
Yeah, I know that the shields aren't bad, per se, they're just a PITA to have to depend on. I have to dig them out, place them on, aim them into the babies' mouths, reposition them if the babies move, wash 'em off, etc etc. Plus, NIP will be much easier w/o having to worry about them too. So it's a long-run question, not so much an I have to fix this urgently question.
I tried a rebirth bath (kellymom.com suggested this) and it was fun, and the babies tried out the boob for a few seconds here and there. I've also been practicing with the bare boob when they're not *too* hungry. For example, when they've been eating, they move and the shield comes off, I won't put it back on right away, and they'll get a taste of the boob, so to speak. They try, but it only lasts a few half-hearted sucks. Then the screaming begins. It's like they don't notice that the boob is in their mouths because it doesn't stick back as far as the shield does.
Did it take a really long time to get them used to the bare boob? I'm thinking that this will take months if I do it slowly. But I don't want to do it suddenly, in a standoff, so to speak.
