the more your baby goes to the breast and removes milk from the breast himself, the more your supply will be boosted
early mixed feeding very often sabotages breastfeeding, by reducing supply
expressing is not an accurate way to guage how much milk you are making, nothing is as efficient at extracting milk from the breast as your baby
breast feeding is supply and demand, anything that interferes with that demand will reduce supply
best thing to do is feed, lots of skin to skin as much and for as long as your baby wants to

also, try getting in touch with a BFC near you, via the NCT, LLL or ABM
