pumping advice

hi! i’ve been exclusively pumping since my baby was born a week and a half ago. ive been getting between 4-7 ounces each session and i’ve been pumping every 2-3 hours about 8 times a day. i’ve already been able to freeze some and i don’t know if i want to be too much of an over producer but i also want to maintain enough for him to stay on only breast milk. i’m a first time mom so i don’t have much experience or knowledge of how breastfeeding works. any advice on what might be best or should i just continue doing what i’m doing? thanks!!
