Iam using breast milk to increase my supply.. I pump 20 min each two hours.. I get only 20ml..how long it takes to increase my supply?

A. Hai good evening !! For improving breast milk supply have lactating foods - milk diary products, rusk, Bread toast, papaya, chikoo, garlic, garlic milk, mutton kheema, have more water and give direct feed to baby Instead expressing out - the more baby latches the more milk produces.
