So I sat down to tinker today with the goal of switching out the cap of one of my old style bottles (not a fan of the Italian bottles, to soft) with a nipple top. I cut the top of the nipple off and got the tube through, then cut the tube to the right length and added a v cut at the bottom of the tube to prevent suction. When I snapped the nipple into place on the bottle it immediately began auto feeding. Adding a reducer made it worse. It's not hot here, not by a long shot and my juice is a 50/50 blend, so not to thin. The only thing I can think to do is cut a bit more off the top of the nipple, maybe it's just tight around the tube. Any ideas? I don't have to use this nipple, I can go back to using the cap on this bottle but this is just irking me to no end. I have to know *why* lol!
