Please help me mommy's...

Right after delivery, my breast produce lots of milk until overflow. I've been breastfeeding all the time to my lo. But now on the 3rd week, my milk flow is getting lesser, everytime my baby latch, itseems like not enough for him & he will start crying. If I pump now, I only get 2 oz from 1 side, another side not doing its job. Before this I can get more on each side. Please help me how to increase my milk supply mommy's... Thanks.
