A. It could be worms. A worm infection can be suspected if there is a loss of appetite, stomach aches, nausea, vomit or itchiness around anus, sleeplessness, weight loss, blood or worms in stools etc., in that case you can consult with your pediatrician and after required tests you can start with the deworming medicine he prescribes.
