my baby boy is 4 month 14 days old and he did potty once in 3 days please give me some suggestions for this

A. it is o k for baby . Baby may not poop on daily daily basis during this age group . No need to worry for this . Baby may pass poop in 2 to 3 days or may be not pass up to 7 days . Can use glycerine suppository for this . No any other medication needed .
