Refusing the bottle, STILL

Looking for completely out there tips on getting my baby to take a bottle.

Yes, we have tried different multiple types of bottles. We have had the most “success” with comotomo.

Yes, different people have tried, male and female- me out of the house, in another room, at our home, at other people’s homes.

Yes, different temperatures and the bottle wrapped in my clothing

Yes, different nipple flow - anything beyond stage one he gauges on

He took at bottle fine at 5 weeks, then at 7 weeks started refusing. Now at 14 weeks, I return to work Monday... I’m prepared to drive back and forth but lately it seems like he is needing/wanting to eat every 2 to 3 hours instead of 3 to 4.

Any and all advice is welcomed !
