Milk supply

I tried lactation cookies and muffins, papaya fish soup, drink only red date tea during confinement and latch baby only once or twice a day. But milk supply was still low. Everytime pump out jus nice for baby. And sometimes need to supplement 1-2 feed with formula. It was only after confinement and nanny left, I start to latch baby exclusively. That is when milk supply kick in. After latching, I still can pump out milk and build a little stash. I used to envy mummies with alot of stash. Therefore, I would believe the more u latch, the milk supply will come automatically. Also need to relax and be happy, don't be so stress and drink alot of water!
