BREASTMILK!!!! URGENT!!!

Hello mommies! Need help po. I gave birth via cs last dec 2 on my 2nd son at 35 weeks. Naintubate po sya for 1 week and until now nasa NICU pa po siya. I started pumping last Dec 5 nung nadischarge ako sa hosp. Marami akong milk, tapos biglang kahapon and ngayon, every morning nalang ako nakakaoutput ng 5 to 6 oz both breasts na po. ? How do I increase my milk again? Possible po ba kaya sya nag decrease kasi di po mismo si baby naglalatch? Hindi ko pa rin po kasi nahahawakan baby ko. ? I am taking Natalac 3-4x a day, tsaka po M2 Malunggay. Please help. Thanks po.
