Ay alam ko yan, mama, sobrang worrying talaga pag may lagnat ang baby kahit konti lang! 38°C is still considered mild fever, and yes, teething can cause slight temperature rise sa mga bata, pero since laging hapon lang nangyayari at 1 year 5 months pa lang siya, better kung i-check mo na with your pediatrician para sure na walang ibang cause, one of my mum friends thought it was just teething din pala, pero may ear infection pala, kaya mas peace of mind talaga pag nacheck ng doctor. In the meantime, try cool compress, sipain mo ng water, at monitor mo ang temp throughout the day; if it goes higher or lasts more than 3 days, go straight to the clinic na talaga. Sending you hugs, mama, teething phase is tough!
