Summary
Brief summary
SAHMRI Women and Kids are conducting a new survey (MILQ), that will follow mother-infant pairs across the first 12 months of life to find out how South Australian babies are being fed. We would like to find out what is helpful in initiating and continuing breastfeeding, as well as anything that could make breastfeeding difficult. We are also interested in the timing of complementary foods (such as solids and semi-solids) and the types of foods given to babies in their first year of life.
The aim of the MILQ study is to understand how families are feeding their full term infants over the first 12 months of life, and what challenges they experience. We hope to use this information to inform the support services at South Australian hospitals and postnatal care providers. The information collected will also help us understand the current practices for the introduction of complementary feeding.
