The baby refused to breastfeed, probably because he was not used to it since he was a child. You can use a spoon to guide the baby to open his mouth first, and take away the gravity ball straw in the bottle, which is full of milk. When the baby's mouth is open, quickly put the pacifier into the baby's mouth and tilt it slightly, so that the baby can easily suck milk. Just try a few more times. If the baby often cries and refuses to drink the bottle, you can also use toys to attract the baby's attention and then feed it with the bottle. I usually try it several times.
