If she is not crying when she wakes, have you tried to just leave her to resettle herself? My son sometimes wakes up early in the morning, will talk for a bit, then go back to sleep. If she isn't interested in the bottle, then I wouldn't worry about trying to feed her. If she does cry, have you tried just going in and doing shh/pat instead of getting her up and changing her or feeding her? She just may need some help getting back to sleep. Sometimes, if my son just fusses, I wait a minute to see if he can resettle on his own. Crying is different than fussing. If the fussing escalates into crying then definately go in and try to help her resettle. Does that make sense?
