Ay oo, very possible na teething na siya girl, kasi 8 months is around that time when babies start! Ang signs na nakita ko sa amin: excessive drooling, chewing on everything, swollen gums, at yung irritability especially at night, parang lahat yan present sa baby mo. One of my mum friends swears by giving a clean, cold teething ring or even a cold (not frozen!) washcloth para sa baby to chew on, it helps with the swelling and discomfort, plus it keeps her distracted from random stuff she picks up from the floor. Siguro also try some gentle gum massage with your clean finger if baby allows it, sobrang calming for them actually. Patience lang talaga sa phase na ito, it'll pass!
