i learnt that latching is the best. supply will come in gradually. you need to rest well, drink lots of water, hot milo, papaya fish soup, fenugreek seeds to help to increase.
what i did was to just latch my baby latch on. even though i can see no milk. actually the lactation consultant is right. you got milk one just that it is trying to build up. but it does need your help to 'stimulate' the flow.
