here's a suggestion... you could buy a breast pump... that way you can store some breastmilk in the refridge for when you go out... and she can be feed by the bottle. the best kind of nipple for a baby coming off the breast is something that feels/looks like your breast to the baby. playtex is one of the best ones to change from breast to bottle. here's a link:http://www.playtexproductsinc.com/in...nurser.aspjust scrowl down to nipples... there is also the breastfeeding section that will show you what they have for breast pumps, if you decide to stay with your milk for the baby.though what i would do is slowly change her from your milk to formula. or you could try mixing the two... and putting less and less of your milk each time, until she is used to having just formula for her bottle.
