So since I've been pregnant I pretty much cut out caffeine because I became a little sensitive to it so I didn't drink to much of it and avoided it really if I could. And since I had the baby I have cut it out all together due to breastfeeding. But prior to becoming pregnant I drank energy drinks all the time! I just liked the taste. And I've been wanting one so bad lately but I didn't know what one could do to my breastmilk. My son is only partial breastfed I supplement but still I don't want it to effect him. I have had like one can of soda not decaf and been ok but I didn't know about 1 bigger can of energy drink...
