It took me three weeks of trying everyday (and lots of tears) but it finally worked! My LO was taking a bottle once a week since birth then flatly refused at 3 months. She would scream bloody murder if anyone came near her with a bottle. Finally I took some advice and suggestions from this site and it worked.
What worked for us:
Put her in the bouncy chair, sat on the floor beside her.
She could still turn her head away and didn't feel trapped like when she was sitting on my lap.
Tried a bottle of EMB everyday. Only 1 ounce at a time. Threw gallons away, sniff.
Did it in the afternoon after her second nap. (Now she takes it anytime.)
Rubbed a drop of maple syrup on the nipple after warming it up with very hot water. (Honey is not recommended because of botulism, corn syrup could work too)
Used Playtex slow flow silicone nipples on a four ounce feeder with disposible liners.
Put my face close to hers and the back of my free hand against her cheek.
No talking or she smiles and wants to play.
Re-warmed the milk and nipple every few minutes.
After every attempt I showered her with kisses and tickles. She began to associate the bottle with fun rather than torture.
I wouldn't breastfeed her after a failed attempt for at least 20 minutes. I did a diaper change, or played a bit or walked outside to distract her.
Keep trying! A lot of babies seem to go through this phase of rebellious independence. It's like they suddenly grew the brain cell that distinguishes boob from fake-boob. I hope this helps someone out there...
