Ah nak, okay lang na kaunting pag-init at pagmamaga after vaccination, pero kung 5 days na at parang matigas pa rin, better check with your pedia or go to the clinic para ma-assess nang proper, gusto namin sigurado na okay lang si baby, diba? One of my mum friends had the same concern at sinabi ng doctor nila it was normal, pero important pa rin na tingnan talaga. Huwag mag-alala, aaayos yan most of the time, pero peace of mind mo mas importante!
