My DD also never took ebm. i think it will be much harder if you are trying to give it to her, i think my DD also thought it was a game after awhile. you need someone else to try.

i am having supply issues for the first time now, and my dd is also starting to drink cows milk when offered (she is over 12 months). maybe because she always knew that my milk was there if she waited long enough, she wasn't interested in ebm or other milk but now with my milk low she is willing to try.

also, she might only drink small amounts at day care and make up for it when you get home. my DD certainly did when i started work (and she was younger having less solids and i had more milk)

good luck
