My baby is not taking food since 4 days she is taking only milk, banana. In a day how many banana can a baby eat

A. Maximum Two bananas not more than that because if you give too much of banana that a child can easily have constipation because of that so two bananas are sufficient milk as much as you want to but would tell you that this is not a proper food you have to give regular food as well as whatever we eat to survive the child should also have the same
