Oo normal yan, mama! At 4 months, ang poop ng babies ay usually yellow, pasty, at may seeds kung exclusively breastfed, o mas brown at thicker kung formula-fed, both are totally okay. A few of my mum friends got worried din about the color at consistency at dun-realize it's all part ng normal baby development, kaya just keep an eye na hindi constipated or may diarrhea lang.
