Hai! Memang boleh ada keputihan pada bayi perempuan, especially yang baru lahir sampai few months pasal hormon dari mummy masih ada dalam tubuh baby, so it's usually normal and akan hilang on its own. Tapi since yours dah 7 months and jarang keluar je, I'd still suggest check with your pediatrician just to be sure everything's okay, mine always say better safe than sorry, especially dengan benda-benda macam ni.
