Boleh je makan japchae, especially since dah habis pantang period! Tapi check lang ingredients, sometimes restaurants add MSG or too much oil which boleh trigger baby's gas, lagi-lagi if baby still adjusting. A few of my mum friends yang breastfeed pun makan Korean food without issues, tapi slow-slow lang first time to see if baby okay. Kalau baby punya perut okay, no problem at all!
