Hindi ko alam kung exact na science yun, pero based sa experience ko, parang take around 2-3 weeks para ma-establish talaga ang milk supply mo after birth, lalo na if exclusively breastfeeding ka. The first few days may colostrum lang (na super yellowish at concentrated), tapos gradually lumalaki ang volume ng milk mo by day 3-5 or so, pero ang full supply stabilizes talaga after a few weeks of consistent feeding. Kahit after establishing na, ang gatas mo ay patuloy na "nag-a-adjust" based sa demand ng baby mo, kaya ang bodies natin talaga ay amazing!
