To examine longitudinal patterns of child introduction to foods and drinks targeted for restriction by parents and associations between child intake frequency, mother's own liking, child early exposure and child liking for restricted foods and drinks at 5 years old. The study involved secondary analyses of longitudinal data from mothers and children participating in the NOURISH randomised controlled trial. Patterns of descriptive data were examined, and a binary logistic regression model tested for prediction of child liking of a selection of restricted foods and drinks. Brisbane and Adelaide, Australia. Two hundred and eleven mothers and their first born 5-year-old children. The proportion of children who had tried the selected restricted foods and drinks progressively increased from 14 months to 5 years old. Mothers' own high liking for both sweet and savoury restricted foods and drinks predicted child high liking for the same items at 5 years old. Child high intake frequency at 5 years old also predicted child high liking for sweet foods and drinks, but child early exposure did not predict child liking for the restricted items examined. These results challenge the belief that limiting children's intake of foods high in sugar, fat and/or salt will increase their liking for them. Findings instead suggest that restricting children's access to such foods may be beneficial. While further research is required, mothers should be made aware that their own food preferences may inadvertently influence their child's liking for the very foods they are trying to restrict.
