Ang kulay at consistency ng poop ng toddlers talaga ay super variable lalo na pag formula-fed, kaya hindi ka mag-alala kung kaunti o marami basta healthy-looking (no mucus, no blood) at hindi siya uncomfortable! 3-4 times a day is totally normal pa rin for 1-year-olds, marami sa circle ko ganyan pa rin kahit formula-fed na, basta consistent lang siya at masaya ang baby. Since worried ka though, best to show the pics to your pedia on the next visit para ma-put your mind at ease, especially if may changes sa routine niya or if he seems uncomfortable.
