I had kidney stones during my last pregnancy. Yeah. That was fun. Good times. Anyhoo, I did not cut back on coffee after the pregnancy. In fact, with 2 little ones, it’s safe to say I increased my coffee intake. I haven’t had any problems. When I asked my doctor, he said they know so little about what really causes kidney stones and each of us are different, so what may be verboten for some is fine for others. He told me to go to Starbuck’s on the way home. You might be different, but if you love cofffee, I say go for it. Personally, I would rather rip off my arm and beat a barista than give up my coffee.
