Ah mama, importante talaga ang vitamins habang nagbabbreastfeed! A few of my mum friends swear by prenatal vitamins pa rin during breastfeeding kasi sobrang drained ka talaga, I personally continued mine for several months after delivery dahil parang tumatagal ang recovery. Best thing though is mag-consult ka with your OB or pedia para malaman kung ano talaga ang kailangan mo based sa diet at health mo, kasi bawat mama may different needs, lalo na kung may deficiencies ka man.
