breastfeeding

hi mommies.. ask ko lang, if we're not feeling well and nagpabreastfeed tyo, nalilipat din ba sknila yung sama ng pakiramdam naten? or its not true?.. madalas kasing sumama pakiramdam ko like migraine.. im thinking if i need to have my baby take formula milk muna while masama pakiramdam ko tapos breastfeed nalang uli pag ok nako..
