If your breast milk production has decreased significantly, there are a few things you can try to help increase it. You could gently compress your breast during feedings, increase the frequency of feedings, offer both breasts at each feeding, express milk after feedings to stimulate production, and consider using different feeding bottles or formulas if your baby is not accepting the current one. Remember, as long as your baby is producing wet diapers, there is no need to worry. Keep trying different methods and don't lose hope!
