Aw, nako, I feel you, diarrhea sa baby is so stressful! AL 110 is usually available sa major drugstores like Mercury Drug, Watsons, or Boots, pero honestly, better to check with your pedia muna because the cause matters, kung viral, bacterial, or just something baby ate na hindi agree sa kanya. A few of us mums learned the hard way na sometimes the diarrhea meds needed depends on age and kung may fever pa. Hope your little one feels better soon!
