ok so I have a 8 day yr old. My milk is barely coming in. Like literally pouring out.

My sons been on bottle since day 2 of birth due to having jaundice. Now that my milk is in i dont know I kinda wanted to try and pump for him? I wanted him to have the advantages of the breast milk vitamins ya know. But I don’t wana be selfish since he’s doing so well on formula. What would you ladies do? I haven’t had any alcohol since I became pregnant but since his birth I’ve had two red bulls (cravings).. I need advice ladies. Breast milk trial or stick to formula
