DD was the same - I used to be very glad it was not my nipple that she was ripping around in all directions to look at everything!

But we used to have a quiet environment when she was feeding, so people in the room stayed and no one went out. (she was a quick feeder thank goodness) At day care they taught her to hold her bottle very early on and that seemed to give her a challenge to keep it in her mouth. I also found eye contact helped - but only if she was in the mood.

Also if she got totally distracted after only half the feed I would put it up for half an hour and then give her the rest when she was hungry - it seemed to work but it did drag out feeding times. At night she just drank and then fell asleep again luckily.

Hope some of these suggestions help - goodluck!
