I fear that we waited too long to try a bottle with DD. She is 10 weeks and had a rough start with BF that included a tongue tie and using a shield, which she weaned from at 4 weeks. Because of that, I wanted her to become super confident on the breast before we tried a bottle. We introduced it at 6 weeks with no luck and we've tried periodically since then, unsuccessfully. She just gnaws/bites at it and then pushes it out with her tongue. We've tried a few different brands, nipple shapes, etc. Any advice on getting her to latch on a bottle? We've also tried having her distracted and sleepy, but that didn't work either.
