Know-it-all

So my best friend has one child and works in the healthcare field. I also have one child and am 8 weeks with number 2. Morning sickness is kicking my butt and her response is "its too early for morning sickness" she always has some smart ass comment. Lol i know it could be the hormones but really....i keep trying to tell her every pregnancy is different buuuut she thinks she has all the answers. I could really drop kick her its so frustrating. End rant lol.
