Ay, mahirap malaman talaga kung nag-ipin na talaga or just gum irritation lang kasi ang babies ay naturally gumagalaw ng jaw! A few of us moms noticed na when they start drooling more than usual at nag-chew ng lahat (kamay, toys, whatever), that's usually a sign na soon or nagstart na ang teething process. How old is your baby? Kasi usually around 4-6 months pa lang ang signs, pero may babies na mas maaga or mas late pa. Either way, if you're worried talaga or may swelling / fever, best to check with your pedia to rule out anything else, pero most likely normal lang yan hehe!
