This is actually a very common problem. Every often babies of three to four months will start to refuse bottle even when they have been taking them every day with no problems before. I think it is because at around this age the baby is able to show you their preference.
The thing that seems to work best for older babies is to try to make bottle feeding as different from breastfeeding as possible. So face the baby outwards instead of in a cradle position or maybe propped against your knees or a pillow or even in the high chair and encourage your little one to hold the bottle themselves.
And remember that really young babies can master using a cup if in the extreme they won?t take a bottle.
Some other tips that can be used to encourage a baby who is reluctant to take the bottle:
? Try offering the bottle before the baby is likely to be too hungry,
? Wrap the baby in a piece of the mother?s clothing (blouse or nightgown, for example) while offering the bottle (works better for younger babies),
? Instead of pushing the bottle nipple into the baby?s mouth, try laying it near his mouth and allowing him to pull it in himself,
? Try running warm water over the bottle nipple to bring it up to body temperature,
? Try different types of bottle nipples to find a shape, a substance (rubber or silicone), and a hole size the baby will accept,
? Try different feeding positions. Some babies like to sit propped against your raised legs; others prefer not to look at you and will take a bottle better if they are held facing out, with their back against your chest,
? Try to feed the baby while moving rhythmically ? rocking, walking or swaying from side to side ? because this may be calming to her,
? Insert the bottle nipple into the baby?s mouth when she?s sleeping,
? Keep trying, but remember that the baby can be fed with a cup, spoon or syringe if the baby continues to refuse the bottle. Medela even sell a special soft cup feeder which I find very easy to use when supplementing babies,
