Ay oo, teething fever is real kaya valid ang suspicion mo! A few of us mums noticed our babies ran low-grade fever kapag nag-erupt ang molars, plus they got extra droolly, chewed on everything, at swollen gums, so it sounds like your girl might be in that phase. The fever from teething kaya hindi sobrang taas, pero since she's already running hot, better to check with the pedia just to be safe na wala nang ibang cause, kasi 27 months pa lang siya at baka may something else din.
