If your child complains of an itchy bottom (rectal area), difficulty sitting, fatigue, and restless sleep due to anal itching or persistent stomach pain with loss of appetite or frequent indigestion, it might indicate worm infestation. Another sign of worm infection is pica in which you may notice your child eating inedible substances such as mud. Speak to your child’s doctor as soon as you notice any of these in your child. The doctor may ask for your child’s stool and blood samples on 3 different days for examination. Depending upon the reports, the doctor will decide upon the treatment and prescribe your child with medicine.
