Ay, sakit ng ulo habang nagbreast-feed ay common talaga, kaya mo yan, mama! Since you're nursing, best to ask your OB or pediatrician kung anong vitamins ang best para sa'yo kasi bawat mama may different needs, lalo na kung may deficiency ka or something. A few of us moms swear by iron supplements and vitamin B complex dahil tumaas energy namin and the headaches lessened, but kailangan talaga ng doctor's advice para sigurado na safe sa baby at sa'yo.
