Hi, My 1.5 year kid has some vomiting and poor appetetite 2 week ago which was cured after some medicines. but again after 3 days of curing he has some red blood in his poo at the end of poo in size of a pea seed. My doctor told may be it is due to cow milk his mother consuming and have given vizylac, zinc multivitamin, metrozyl, and albendazone. but the problem still exists but sometimes blood is present sometimes not. He has the similer problem previous time he was teething, now again he is teething. he has some cough too. Please suggest that what should be the reason of blood as i am worried.
