So today I was feeling very tired and unenergized, my husband offered me a rockstar energy drink and I didn't think much of it and took it thinking I hadn't had my cup of coffee anyway. About 2 hours later after I pumped, I happened to read the warnings on the can and it says that it is not recommended for pregnant or nursing moms. So now I have about 4oz of breast milk that I don't know if I should dump or if it's still safe to feed to my 9 week old baby. Any one know the effect the rockstar may have had on my breast milk? Will it harm my baby if I feed her this milk?
