How old is your baby? I love matcha and sometimes latch baby almost immediately after drinking. The caffeine in Nescafe capsule is relatively low.
Again, it all depends on how your baby reacts to caffeine. A baby who is being overstimulated by caffeine is a wide-eyed, active, alert baby who doesn’t sleep for long. He may also be unusually fussy.
If your baby seems particularly wakeful or fussy and there is a significant amount of caffeine in your diet, you might want to cut back or stop the caffeine for 2-3 weeks to see if it makes a difference.
If you cut out caffeine, consider decreasing it slowly since abruptly stopping caffeine can result in headaches or other symptoms.
If caffeine stimulation is a problem for baby, it may take a few days to a week after mom eliminates caffeine for baby to become less fussy.
