Mama, please bring baby to the doctor or nearest health center agad-agad, lalo na kung may fever or swelling pa, hindi normal yan kahit common ang slight redness after vaccination. Better safe than sorry, diba? Pwede ring allergy o side effect na kailangan i-check ng doctor right away para sa peace of mind mo. Keep baby comfortable muna habang naghihintay, at monitor ang temperature at behavior. Sending you hugs, know how scary yan pang-first time mom.
