My daughter is 2years and 4 months old, for the past 7 days she is not passing stools in normal way. Before she was passing stools regularly but since 7 days she is passing it on alternative days. And when we see her stomach it seems full and bloated from outside but is soft when pressed.  She takes formula feed and some breakfast like upma/ Paratha , rice dal in lunch and Dalia at dinner. What should we give her to get her back in normal lifestyle. Should we give her probiotics or what medicine ?
