Baby being difficult about feeding

I posted this in another group but have had no answers, hoping to get some here: My baby is a week old, and he is bottle fed breastmilk. Whenever we give him the bottle he will feed from it then pull away, just to immediately cry and start rooting again for the bottle. He also lashes at the bottle and will cry while the bottle is I'm his mouth before realising the bottle is there and latching. Currently he has been doing this for over an hour and only consumed about 1oz. He doesn't want his dummy at all he wants the milk but he keeps doing this. He was way way worse on the breast when we tried it. Anyone know why he does this?
