I need help 😭

My baby is two weeks old tomorrow. However he is just continuing to lose weight. I feel like I have tried everything. All I do it feed him. Every time he unlatches he seems satisfied and there is still milk in my boobs. But he still is only getting about an ounce at each feeding. I want to stay away from formula as long as possible. If anyone had any tips or suggestions I’m open to try anything. I’m seriously desperate.
