is solved by adding more fluids to the diet,fruits,fruit drinks and fibre from vegetables.Try to accomodate these products in your diet. Bonnison does not help at all.Please try to avoid products like this.Use a paed glycerine suppository if possible.If the prblem still persists consult you doctor.
Usually increased water in the diet solves the problem
Hope your child gets well soon.
