I thought I could drink this while breastfeeding?

I don’t usually ever drink energy drinks but I thought I’d buy a few sugar free Red Bulls to have every once in awhile.

I see this on the can? Not recommended for nursing women?

I drank a cup of coffee this morning. My baby never seems sensitive to if I have any caffeine or not. Is this ok for me to drink if I only had 1 cup of coffee today? 114 mg of caffeine doesn’t seem like that much more than a cup of coffee?
