Nipple Shells?

Naomi

Hi ladies

I have a 5 weeks old, we have used a nipple shield since birth due to flat/short nipples. I keep trying to nurse without the shield and he won't latch on, because he has nothing to latch on to. If I have to use the shield forever I will but I'm wondering if nipple shells will help us be able to nurse without the shield. Anyone have experience with shells, did it work, what brand/type did you use?
