DL to Bottle

My baby is going to infant care in a month time but she still do not want bottle. EBM in bottle. She will suck abit and then pull out and then no more. The most she drank is only 10 ml. We kept trying. Got a feeling she is okay to use the nipple we used to feed her with when trying. What else can i do? Will the teacher there able to train her when she is in unfant care or will she be rejected in the center? Worried mum here..
