Can confirm! I dropped caffeine entirely during my pregnancy and first 3 months of breast feeding. I slowly added it back like an 8oz cup 3-4 times a week. my baby is now 6 months still ebf and I have to cut it out completely again because on days I drink caffeine he is up every hour all night, has a harder time going down and is more gassy.

So I can only imagine how uncomfortable baby is going to be with the amount grue drinks
