Baby Weaning Supplements?

So we got my daughter up to 2oz supplements of pumped milk or formula bottles after nursing (this was after I was sick with a stomach bug that totally tanked my already low supply which was already being supplemented). When we were at the pediatrician last for her two month check he told me she would wean herself off the supplements which I really didn’t believe because we were giving her so much. Well this week she has been self-weaning and only took 2 whole supplements today and half an ounce from another bottle. It would be ok to only offer her an ounce, right? I can just have more available one ounce bottles if it seems like she’s hungrier. It is so much work to pump two ounces.
