She will, if hungry
A healthy baby will eat or drink when she is hungry.
So, parents can't make a baby eat, they can only let her get hungry. She will eat when she gets hungry enough. If she is usually bottle-fed, she will drink if she hasn't eaten a while. If she eats often, she may not take the bottle because she is still full. If she will breast-feed but not bottle-feed, she will take the bottle if hungry enough.
