This could well be a problem of either cow's milk protein intolerance or true allergy to cow's milk. All the symptoms are highly suggestive of severe cow's milk protein intolerance. I strongly suggest that you see a paediatrician with an interest in allergic conditions in infants. There are experts in all the main centres in South Africa. In the meantime do not let him have an another antibiotic under any circumstances!Give him probiotic drops such as Reuteri Infant drops once daily for at least 10 days while you are waiting to be seen by the paediatric allergist.
