9 month old won’t take bottle

Hey ladies... I just came back to work with week after being home with my baby for 9 months. I’m still pumping during the day and nursing him at morning/night. But he won’t take the bottle. He has had the bottle before, when he stayed with family. But maybe a total of 10-15 times. He had Dr Browns, and Avent. Last night i brought platex with the bag because I heard it was better For transition. But he still won’t drink. He will eat his solid foods all day and no milk. I’m pumping all this milk and he won’t drink 😫. We Tried his sippy cup also. Nothing!! Anyone have any suggestions. Please. Thanks
