Thank yo for the query.
By the description it seems your child is suffering from
anal fissure which usually results from hard motion. Passing hard motion is very common i children as they are weaning, mostly take milk and very little of water and vegetables.
This indeed is a very painful condition.
You can apply Vaseline at the
anal canal and push a bit inside. This will act as lubricant and smooth passage of stools. Apply this for three to four times a day even if not passing motion for a few days.
You can also administer pediatric
glycerin pessary half an hour before his usual time of passing motion.
Apply Anovate ointment at anal passage - once after passage of motion (after cleaning the child) and once at night.
Continue to try adding fluids, vegetables and fruits to the diet and increase its amount regularly, as advised by your current doctor. This is the only remedy in long term.
If he has started walking, let him walk and run continuously, this will add up to the exercise and improve bowel movements.
