So I have a six year old that I didn't breastfeed due to being on high amounts of antibiotics due to bad kidneys. So I am pregnant again and financially my husband feels breastfeeding would be best, plus our insurance will actually pay for a pump. I am still nervous though because of my kidneys and the antibiotics. So is there anything I can do to test the milk? Like there is for alcohol? I plan to talk to the doctors at some point its still early just trying to figure out if it will be worth it

Thanks
