my baby is 3 months 12 days old and completely on breastfeeding. she is passing the stool since 5 days please advice

A. it's ok. it s absolutely normal for the baby to not pass stools daily as digestion process can be different for all . If baby does not pass stool even upto 1 week it s not to worry. If more than 1 week and baby has discomfort can use glycerine suppository for relief.  No syrup is given for this below 2 years for this issue .
