Ay, depende talaga sa kulay at consistency, mama! At 3 months old on formula, normal poop can range from yellow to tan to greenish, and it can be pasty or even a bit lumpy, pero kung consistent lang siya at baby mo is happy, gaining weight, and wala siyang signs ng discomfort, most likely okay lang yan. A few of us in the mums group always say observation is key, kung nagbabago drastically ang color, may mucus, or very watery, or kung mabigat ang amoy or baby seems in pain, best to check with your pediatrician para sure lang, kasi it's better to be safe with babies natin, di ba?
