Uy, mama, a sunken fontanelle (ang soft spot sa ulo) with fever needs a doctor's check ASAP, hindi ito dapat i-DIY, okay? It could mean dehydration or something else kailangan ng proper assessment, kaya please bring baby to a pedia or emergency room na, lalo na may fever pa. I know it's scary (been there, ang aming baby fever days were stressful!), but ito talaga kailangan ng professional, hindi lang home remedies. Hang in there, mama, the doctors will figure out what's going on.
