Hi Audra, some tips to keep your DD feeding - try stroking under her chin or behind her ear while you are feeding her. With Molly she doesn't normally like to have her head stroked so I have found that this annoys her enough to make her suck. She doesn't wake up, it just seems to wake her enough for her to realize there is a bottle in her mouth!
Also, I think I read in the BW book (could have been another book though I'm not sure) to try "walking" your fingers up and down their back. Don't know if this tickles them or what but it does seem to work as well.
The other common tricks are to rotate the nipple (if you are bottle feeding that is, heeheehee) or to try to pull the nipple out when she stops sucking. Sometimes that will help.
Good luck!
