Increasing intake

How did you know to increase the amount of formula/BM given in a bottle? My almost 8 week old has been getting 3oz of breast milk during the day and 3oz of formula at night since I don’t produce enough milk. During day he’s started crying for more at about an hour an a half mark. Time to go to 4?

He slept 5 hours after a 4 oz bottle last night! First time ever.

Also- has anyone ever read moms on call or suggest any other sleep books?
