Hi, my niece who is 1 year 9 months old now is going through indigestion these days. She is passing stool almost 4-5 times a day and the consistency of stool is quite ok, no watery stools are there. She is currently going through medication  Can you please tell me what are the general causes of indigestion in toddlers? And also what should be her diet now like what all things should we include or exclude? Thank you in advance
