Objective: This is a retrospective cohort study to investigate children’s food habits, affecting changing their likes/dislikes, on the basis of questionnaires answered by the mothers of 222 children. 
Methods: The questionnaire data was analyzed on 4 years old children at the beginning of the first year of kindergarten and on the same children at the end of the second year, when they were 6 years old. The questionnaire included 18 questions regarding their children’s lifestyle, likes/dislikes, attitude toward foods and guardian’s food habits. The Kruskal Wallis test was performed to compare the ordered categorical outcomes among four groups of changes in likes/dislikes: “(+) to (−)” means that the children disliked some foods as 4 year olds, and that as 6 year olds they disliked no foods, “(+) to (+)”, “(−) to (+)”, and “(−) to (−)”. 
Results: In total, 71.0% results reported (+) to (+), 10.0% reported (+) to (−), 6.5% reported (−) to (+) and 12.5% reported (-) to (-). Among the four groups, “Respect for food” (p<0.001), “Enjoying school lunches” (p<0.01), and “Family’s deviated food habits” (p<0.01) significantly varied. Children in the “(+) to (−)” group showed significantly more favorite behaviors than in the “(+) to (+)”. 
Conclusion: Changes in children’s likes/dislikes during kindergarten 2 years’ course may be related to “Respect for food”, “Enjoying school lunch” and “Family’s deviated food habits”. Therefore, managing these habits may be important when trying to change children’s likes/dislikes.
