Baby won’t sleep😩

Girl mommy💘 • O1.16.19 my hunniebunnie arrived 💖

Today is the first day so far that my baby hasn’t been asleep like she usually does and all she wants to do is eat!!! I am breastfeeding so today/right now, tonight, I’ve been feeling crazy almost, I can’t get rest or do anything but feed her. I just gave her 2oz of Similac to see if that would do the trick, but she still wanted more!! Plus I’ve been feeling sick to my stomach which is awful. It’s not cramps, I’m 3weeks pp, any idea?
