Ay, normal lang yan sa 5 months old, lalo na kung mixed feeding, marami kaming kaibigan na ganyan din ang experience, especially pag biglang nag-introduce ng solid or formula adjustments! Pero since nag-change lang siya this week at mas frequent ngayon, mas safe na i-check with your pedia just to be sure walang tummy issues or allergy, kasi bawat baby talaga ang iba, better peace of mind din for you, lalo na first time mom ka pa!
