A. I believe you should give more of liquids and fibre in the diet of your child because constipation in growing age increases if it is not treated correctly from an early age and along with that start applying a drop of castor oil in the navel before sleeping and start the day with a glass of warm water and in the night you can also give 30 ML of prune juice
