One thing I learn when bf, you have to drink a lot and eat well.
For moms like me, whose supply is not a lot, we have to work harder.
During your first few months, drink a lot of soup. All kinds (of cos the best they say is papaya and fish soup.) as you bf, you lose water, so need to replenish your body with water and soups contains a lot of nutrients good for your bb.
Eat well too.... Carry on to take calcium pills after giving birth and also eat a lot of fish. It helps to produce milk. That is what the lactation nurses taught me.
For lucky moms, I saw a few, their milk is so much ... so envious and they don't need to work on it .. just come naturally. After 4-5 months, when your supply is established, your body knows it needs to produce that amount of bm, supply will just come naturally.
