Bottle for baby that breaks suction?

My baby always breaks suction while drinking and takes in a lot of air, he doesn’t flange his top lip out either. The doctor said he doesn’t have a lip or tongue tie. We have tried different positions, bigger and smaller teat flow, nothing changes. We have tried 8 different types/brands of bottles. I would just like to know if anyone has had this happen with their baby and what bottle worked best for your baby?

Tia.
