This happened to my neice and all she could do was send milk and hope she drank it. It took a couple of CC days, she was only going a day a week, before she took the bottle.
It didn't harm her and they offered her water or the bottle during the day so it was not lack of trying on their part. In the end she just rode it out knowing she would feed well when picked up.
Her little one was a few months older so not sure if that will make any difference. She might take the bottle for them as she cannot 'smell' you for her milk.
