Nipple shield

Rachel

Does anyone nurse with a nipple shield? We have since my little man was born tongue tie and flat nipples. Wondering if anyone knows a bottle nipple similar to the nipple shield? Landon won't take a bottle, we've tried different people feeding him and different times of the day. He just plays with it and pushes them out of his mouth. He also won't take a paci, he doesn't know what to do when it's not a breast I guess :-/
