Should I just try to give her all ebm in bottles for one full day?
She's a little small for this -- it can be rather traumatic for LOs, especially if she has no interest in taking it and will most likely end up very hungry and very mad! I was able to get my dd1 to start taking the bottle again around her age by offering it every day before every feed (with only an ounce or so in the bottle) and when/if she refused, nursing as usual. It took somewhere around 2 weeks, but she did eventually take the bottle like a champ, without any of the trauma of withholding food from her. Then, you have to make sure that you keep giving the bottle regularly so she won't start refusing again. They can get to the point of bottle refusal so quickly at this age!
