I stopped drinking coffee, coke and tea when I found out I was pregnant, instead eventually opted for decaf coffee or tea which I steeped myself weak. I only drank decaf when I was breastfeeding too, at least until my son went down to 1-2 feeds a day and my coffee consumption was outside of his schedule. Now I looooove my coffee.
If I get pregnant again, I plan to stop drinking coffee again as well. Despite this study and that study, caffeine is, in fact, a drug. I like to give my unborn child the best chance possible. That`s just me.
