Re: Im torn :(
I use a shield with my daughter. She had trouble from the beginning latching on and is now 3 months and will still not latch to just the nipple. She also goes very easily back and forth between the bottle and nursing. I think the shield has helped with that because it's not as much of a difference. I'm not sure if they are sized by your nipple size or the size you want for the baby. but I have the best luck with the small one from medela. It is 20mm. You can't get the small one everywhere, but toys r us has that size. It might really help getting her switched.
