Hello and welcome to Chat Doctor. The behavior your child is exhibiting is encopresis (pants soiling). Most commonly it is due to Fear of loo which develops secondary to Painful def evasion (bowel movements). Painful defecation most commonly is due to constipation. Treatment involves removal of impacted stools from gut by giving enema or glycerine suppository (medicine given via anus)After that constipation is treated by lactulose syrup and increasing fiber and water intake. Also get your babies' rectum (last part of large gut)checked by pads surgeon. Treatment also involves behavior modification for bowel movements and fear of loo. It is done by psychotherapist Hope you find this answer satisfactory. Good luck.
