How many oz of formula/breastmilk per day?

DS is going through a nursing strike. He's been on bottle strike since he was 2 months old. -.- I pumped this morning and he drank about 4 ounces straight from a cup. That's the only way little homey seems to wanna drink. -.-

He eats solids like a champ and I'm wondering how much milk (minimum) I need to give him. Will continue to offer boob throughout the day, but 1.5 months til he's 1 so I' don't wanna stress myself out too much over this.

Gahhh.. funny how my kids are so different! DD nursed til she was 2+ yo and wasn't big on solids. -.-
