Description of intervention(s) / exposure
The aim of this cross-sectional national survey is to explore the early life feeding practices of infants and children with cystic fibrosis in Australia, with a focus on exclusive and partial breastfeeding rates throughout infancy, determinants to breastfeeding cessation, infant formula introduction and the timing and practices associated with transition to solid foods. The project duration is 6 months. Mother/primary caregiver will be asked to complete the survey. The survey will only be completed once. Survey duration is ~ 10 mins.

Eligibility
Key inclusion criteria
Mother/caregiver of cwCF <2 years of age (i.e. 0-1.9 years of age) living in Australia during the designated 3 month study period and receiving their CF care at one of the included sites. Mother/caregiver must have sufficient English language to complete the survey. Alternatively, if an interpreter has been booked for the duration of the CF outpatient clinic as part of routine clinical care, then the interpreter could facilitate consent and completion of the survey.

Statistical methods / analysis
To determine an accurate statistical prevalence of breastfeeding in infants and cwCF living in Australia, with a confidence interval of 0.05, a standard error of 0.03 at the 95% confidence interval, a sample size of 95 participants is required. The project duration of 6 months is sufficient to gain statistical significance. Raw data will be exported from Qualtrics Plus. Appropriate descriptive statistics (depending on distribution of data and continuous vs. categorical variables) will be provided following cleaning and coding. T-tests, Chi-squared as well as univariate and multivariable and/or logistic regression models will be used to identify associations between infant and maternal characteristics and exclusivity and duration of breastfeeding; precise statistical methods will depend on number of responses. A p value of <0.05 will be considered statistically significant.
