Uy, super relatable yan! My son was exactly like that around that age, kaya I tried a few multivitamins, mga friends ko swear by Ceelin or PediaSure, pero honestly ang real game-changer para sa amin was just consistent meal times and letting him see us eat, kaya parang gusto niya sumali. Definitely check with your pedia though kung concerned ka sa nutrition niya, kasi sometimes picky eating is totally normal sa age na yan, pero better safe than sorry, right? Good luck, mama, alam ko frustrating yun!
