Do you throw away your foremilk?

Ch

So I have a lot of foremilk, i exclusively pump 20-30 minutes 4-6x per day. I noticed my LO is always gassy and sometimes even has spit up. I read somewhere about perhaps having foremilk/hindmilk imbalance. So I have been getting rid of most of the foremilk atleast 4 ounces from each pump session. Do you ladies think this is ok? Or am I just wasting precious product 😩. I produce enough for her right now, about 40 ounce per day ( after getting rid of the foremilk) and she only eats about 20 ounces
