Breast Milk Bottle

I made a bottle to try and introduce to baby. I immediately put it in the fridge for night time feed. We took it out about an hour before her feeding and put it on the counter to get it to room temperature. The introduction didn’t go as planned and she drank maybe 1/4 of an ounce. I put it back in the fridge to try again. But, now I don’t know if it’s okay to use still. Or if I should just dump it. Also, should I give the first bottle to see if she will take it, or should dad try the first time?
