Ay, normal lang yan, mama! A few of us went through the same thing after the vaccine, ang baby namin nag-fever din within hours, then ngiti-ngiti na ulit the next day. Ang lagnat na on and off like that, especially if masaya pa rin siya at kumakain ng maayos, usually yan lang ang body's way of reacting sa vaccine. Most babies bounce back within 24 to 48 hours, so if okay na siya ngayon at walang fever, signs na tumatak na ang vaccine sa sistema niya. Since she's eating well at active pa rin kahit may sinat kaninang araw, that's actually a good sign! Pero since scheduled na nyo ang pedia bukas anyway, okay din i-mention yun para sa peace of mind, lalo na first time, naturally worried tayo. Take care!
