Uy hi! Honestly kailangan mo talaga i-check with your pedia or OB about this one because kahit common ang Tuseran, depende talaga sa ingredients at kung safe pa while breastfeeding, better safe than sorry, lalo na with baby meds! A few of my mum friends nag-ask din ng alternatives sa doctor nila instead, so baka may safer options na pwede recommend ang doc based sa ubo at sipon ng LO mo, kaya seryoso lang i-consult muna bago uminom. Good luck sa baby mo, I hope malusog soon!
