Yes, stop bottles asap. Its very hard, but you need to stay calm too. Your doctor and or insurance company should have a list of lactation specialists that can help you.
Try a nipple shield that should help you
Call La Leche League or your ob-gyn and ask to see a lactation specialist. Don't wait, you need to fix this.
I'very never had a nipple confused baby, but have successfully breast fed 6 babbies. I'd start in the morning by stopping the bottles. It's only making him more use to that. Newborns will suck on almost anything. Be patient with yourself and give your milk a chance to let down. Also call the hospital or a breastfeeding group for further advice. I know there are a lot of support groups out there for breastfeeding moms. God bless you and your new little one.
