3 months 5 days baby girl formula milk feeding 60 ml per 4 to 5 hours... how to increase feeding?

A. Main this time even if this child is taking feeding in 4 to 5 hours is not a problem but it should be at least a minimum of 90 ML so try to give straight 90 ML and see if that helps because sometimes kids once they quit on the bottlefeeding whatever amount they have the bottle they do not accept it again try to straight start with 90 ML and see if that helps
