Eh tu normal je, baby aku pun baru ada gigi at 8 months, some babies memang lambat sikit! Kalau baby aktif je dan makan well, takde masalah. But kalau you're worried, best check dengan pediatrician lah just to be sure semuanya okay dengan development dia, a few of my mum friends went for checkups jugak when they were anxious, and it gave them peace of mind je.
