Hi Lakpa Tshering Tamang
Welcome to HealthcareMagic.
How is her diet ? If she is taking good diet and still not passing stools , even otherwise , it could be something serious.I advise you to visit your
Pediatrician as early as possible.Do not worry about it but do not neglect it too.With more information , it would have been easy for us to assess the condition.
Take care.
