 Secondary outcomes include the incidence and severity of diarrhea and acute respiratory infections over the first six months of life, clinic utilisation for illnesses during the first six months, and growth over the first six months. Episodes of diarrhea, dysentery, acute respiratory illness ARI, and clinic utilisation will be based on a maternal interview conducted every two weeks. Diarrhea will be defined as 6 or more loose, watery stools in a 24 hour period. Dysentery will be defined as diarrhea with the additional history of blood or mucus in the stool. The incidence of episodes as well as their duration will be assessed during the data collection process. Growth will be assessed only at the six-month visit where weight, length, and mid-upper arm circumference will be assessed using standard protocols.
