hi you can do breast massage by having a warm towel on your breast. also, do breast compression method when u feed your baby. it helps to improve the milk flow too. also, domt wait until baby is crying and then offer the breast. e.g. feeding time is 2pm and do it at 145pm when baby is no so hungry and have more time to prepare it too.
you can massage before feeding your baby to trigger the let down. if you're low supply try doing lost of skin to skin during feeding it helps. need help can pm me at my IG @mummyjlife I manage to get back my supply when my girl is 13 month old.
