Aw, normal lang yan mama! Formula-fed babies usually have thicker, pastier poop compared sa breastfed babies, at mas madalas may slight color variation, so don't worry. A few of us mums noticed na pag NAN formula, ang poop ay medyo yellowish-brown or tan, which is totally okay as long as wala siyang signs like hard stool, constipation, or blood. What matters is kung active pa rin siya, gaining weight, at wala siyang tummy pain or diarrhea, pero kung you're still worried or napapansin mo something off, mas better to check with pedia mo para peace of mind!
