I have evaluated your query thoroughly .
* Cerelac ingredients are known to produce side effects in form of   
constipation   or 
diarrhea  in many cases .
* Suggestions  for  your  toddler 
  -  Avoid  any type of cerelac at present 
  -  Breast feeding  of mother is perfect at 6 months 
  -  In  addition  give  all green vegetables juice , rice water , coconut water
     lemon juice , boiled  water , butter milk   which  will boost  up  hydration
     level  along  with  digestive  power  of the intestines .
  -  Regular 30 minutes burping  after feeding .
  -  Addition  of  digestive  enzymes  also  help .
Hope this clears your query .
Welcome  for  further assistance  .
