Bottle amount

Hey everyone!

So I rarely bottle feed my baby. Right now I needed a little bit of a breast break so figured I'd pump a bottle for hubby to feed him. He is almost 3 months old & is almost 16 pounds. Recently in a mom forum there was a huge post about how one of the moms was mad her husband gave her baby more than 4 ounces of breast milk from a bottle during one feeding. The other moms replying were stating how a baby only ever needs this much no matter the age. Is this real? Only asking because my chubby man cries for more after he finishes the bottle and won't settle for a binkie. He downs the bottle!! I don't want to upset his tummy if this is really the case by over feeding him, but also don't want to give him to little. I formula fed my other two and they would always pull away when they were done.
