The present analyses were restricted to children with follow‐up at age two years. Milk consumption was evaluated by parental telephone interview, and its association with socioeconomic factors was studied.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>The 12 341 analysed children had a mean age of 26 months; 50% were girls. Rate of <jats:styled-content style="fixed-case">IFF</jats:styled-content> use before two years old and at two years old was 65% and 43%, respectively. At age two years, use of <jats:styled-content style="fixed-case">IFF</jats:styled-content> was lower with young age of the mother (adjusted <jats:styled-content style="fixed-case">OR</jats:styled-content> [<jats:styled-content style="fixed-case">aOR</jats:styled-content>] = 0.4, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content>: 0.3–0.5), low educational level (<jats:styled-content style="fixed-case">aOR</jats:styled-content> = 0.7, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content>: 0.6–0.9), high parity (<jats:styled-content style="fixed-case">aOR</jats:styled-content> = 0.3, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content> 0.2–0.4), and mother smoking (<jats:styled-content style="fixed-case">aOR</jats:styled-content> = 0.8, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content>: 0.7–0.9) as well as low household income (<jats:styled-content style="fixed-case">aOR</jats:styled-content> = 0.5, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content>: 0.4–0.7), and parents’ unemployment (<jats:styled-content style="fixed-case">aOR</jats:styled-content> = 0.7, 95% <jats:styled-content style="fixed-case">CI</jats:styled-content>: 0.5–0.9).</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>In this national population‐based study, the rate of implementation of the <jats:styled-content style="fixed-case">ID</jats:styled-content> prevention strategy was much lower at two years old than before two years old, and significantly lower in disadvantaged populations.</jats:p></jats:sec>
