Have confidence in knowing that this is a very common issue. I belong to another website as well - www.babywhisperer.com.
Below is a lit of suggestions from that website, I thought might help.
"*Be positive approach the feed "knowing" baby WILL take it from you. Baby will sense your confidence. If you get stressed or negative it will /can fail.
*Remember that baby is not refusing the bottle on purpose.
*Sit your baby on your lap and talk to him, “It is time for your bottle. Look how yummy" etc. Keep the positive talk. Stress and negative vibes can be felt by yout baby. Take deep cleansing breaths and keep reassuring yourself and your baby.
*Remember, your baby will not starve herself/
*She (Tracy) suggested using the Haberman feeder so that baby can regulate flow. She suggested holding baby close, like when b/feeding, and having your fingertips on her face to provide the skin-to-skin contact babies get when b/feeding. Tracy also advised walking with the baby if she fussed during the feed, and 'jiggling' her a tiny bit.
*VERY warm milk
*Start on breast or pacifier or finger then slip the bottle in after a minute or two..
*Cut out the distractions! No TV, dim the lights, etc.
*One day, at about 9 wks, I gave her nothing but bottles of ebm. The first bottle took an hour, with problems. She only took maybe 2 oz. Since she was on a roughly 3-hr schedule for feeds, I made her go the 3 hrs until the next feeding (she was REALLY hungry.) Bingo! She took the next bottle with no fighting, and downed 4 oz. in 10 minutes! The third bottle that day was actually her first trial of formula. Again, no fighting, and she took 3-4 oz. very efficiently.
*Hold baby in the crook of your leg (my left foot resting on my right knee) so that she's not right next to the real thing
*Tickle the roof of her mouth with the nipple and then lift the bottle up
*Feed in a different place/room (i.e., bouncy seat, car seat, high chair, your bedroom, living room, kitchen, etc)
*Try different bottles/teats. Look at your own nipples and try to find one that matches the shape of your nipple when baby is feeding
*Let your baby put her hands around the bottle herself.
*Try a sippy cup, maybe without the stopper (so there is no sucking needed)
*Start when baby is not hungry, perhaps 30 minutes after a bf to get used to the nipple and the bottle. Eventually offer for a feed.
*Used a nipple with the same shape as the pacifier
* Be persistent
*Have someone else offer the bottle, and take the time to go out and do something for yourself (so you don’t hear the battle, if there is one)
*Try it cold (if teething they may prefer something cold)
*Mommy has to be out of the room where baby can't see or hear her. Daddy gives the bottle; take off his shirt and strip baby down to her diaper when he feeds her so that she gets the skin-to-skin contact that she gets with Mommy. There are no distractions and he gently talks to her while feeding her and lightly bounces her while she is cradled in his arms.
*Get them used to the taste of formula by dripping formula into their mouths.
*Drip the milk from the teat so that they know it is the source of food supply and keep doing this until they latch on.
*Hold down both hands so that they can't push the bottle away.
*Put it in the corner of their mouth rather than the middle and rest it on their gum.
*Try and calm baby down from real screaming with cuddles then try again.
*If weaning to formula, try mixing EBM with the formula. Make the formula first (so water to powder ratio is correct) then add EBM. Try ¼ formula and ¾ EBM. Slowly adjust the ratio of formula to EBM until full formula
Start at an early feed. Baby will be more hungry and perhaps more accepting.
*Stand in front of a mirror so baby can see himself
*Give the baby the bottle for 5 minutes, then take a break for 20 minutes, try again for 5 minutes and after that, nurse. Do this 2 times a day for a week. Make the 5 minutes fun and set a timer so you’re not watching the clock
