I am freaking out. Ugh. I have mastitis, and I'm allergic to penicillin, so my OB prescribed Bactrim for me. I took my first dose and fed him, as my OB instructed me to do so. Well, I started wondering if Bactrim was safe to take while breastfeeding, as I found some conflicting information. I called the on call pediatrician. The ped said since he is under a month old, I'm not to breastfeed while on Bactrim. Wtf?? I literally can't believe my OB prescribed something that isn't safe!!

So now I'm to pump and dump and feed him formula. We have some ready to feed similac here, but I literally have no idea how to do this. Should I be mixing it with pumped breastmilk at first? I have a measly 3 oz in the fridge that I can use. This is a nightmare, especially when I'm this tired and have a fever any advice would be appreciated, as the ped didn't really give me much information about how to introduce formula.
