Oo, pwede naman ang tahong habang nagbreastfeed, walang problema doon! A few of us moms actually eat seafood regularly habang nag-nurse, kasi yung baby mo ang nakakakuha ng nutrients from your diet pa lang. Just make sure fresh lang siya at properly cooked para sure na walang bacteria, at kung may allergy history sa family ninyo na seafood, observe lang kung may reaction ang baby, pero generally okay lang talaga.
