Yes, you can drink green tea while breastfeeding, but moderation is crucial.
Green tea is known for its antioxidant properties. However, it contains caffeine, which can pass into breast milk and may affect your baby.
Research suggests1 that excessive caffeine intake can lead to symptoms such as irritability and sleep disturbances in infants. While the caffeine content of green tea is less than that of coffee, it's still present and can accumulate in your baby if consumed in large amounts.
So while it's okay to enjoy green tea, it's recommended to limit your intake to prevent any potential adverse effects on your baby.
