My little one is 5 months old, recently he was suffering from viral infection and due to that had temperature in the range of 98.5 to 100.4 C. Doctor had put him on on Combiflam sos basis and Augmentin suspension for 5days. After passing 4 days on medication he has not passed stool for 3 days previously he used to pass stool daily,  his diet has gone down little not very drastic Chang in diet. I would like to know whether it is normal not passing stool for 3 days? Secondly, home remedies suggest that castor oil can be given in such conditions, please advise if castor oil can be given to a 5 months baby. Thank you
