My baby boy is 1.7 years old weighing 9.4 kg. For the last 2 months whenever I do not make him wear diaper or pants he put his fingers into his anus and then put his finger into mouth.I always keep his genitals clean and dry and limit the use of diapers to the best possible extent.Also apprehending worms, I have also administered No Worm medicine as per Doctors consultation.But still he is showing the same signs. Pls Doctors and moms kindly suggest and help me out.
