Objective: Early cessation of breastfeeding and introduction of solids is common in Australia, which may have implications for child growth and obesity risk. This study aimed to contrast usual energy and macronutrient intake of infants against requirements according to feeding modality (n=670) and determine whether early introduction of solids and cessation of breastfeeding were independently associated with rapid growth (weight gain z-score ≥ 0.67) between birth to age six months (n=220). Methods: An analysis of data from mothers and infants participating in the NOURISH and South Australian Infant Dietary Intake (SAIDI) studies was undertaken. Both studies enrolled mothers on the postnatal wards from 11 large hospitals in South Australia and Brisbane consecutively. Anthropometric data, infant feeding practices and three days of infant dietary intake data were collected at birth and again when infants were aged 4-8 months. Results: Usual energy intakes were above estimated requirements for infants aged 4-
