Ay, early pa yan mommy! Usually teeth start showing around 6 months, but a few of us have babies na nag-drool at gumagalaw ang gums as early as 4 months, so hindi impossible. Check lang kung red, swollen, at napakainit ang gums niya, o if she's constantly chewing on her fists, those are telltale signs na possible teething na talaga. But honestly, best to ask your pedia during the next checkup just to be sure, because may iba pang reasons din bakit ganyan ang babies at ganitong edad!
