This study investigates the relationship between infants' breakfast eating habits (296 kindergarten and 145 nursery school infants) and the dietary awareness of their parents (mostly mothers). The results show that most of the infants went to bed and woke up at regular times. However, 11% of the infants went to bed at 10-11:00p.m., and 10% had difficulty getting up in the morning. The later they went to bed, the more difficult it was to wake up in the morning. Five percent of the infants did not eat breakfast everyday, 24% of them ate breakfast alone or ate with siblings, and 34% of the infants ate only one type of food. The parents regarded “nutrition balance” as an important element of meals, except for breakfast. They preferred “easy-to-eat” and “easy-to-cook” meals for breakfast, rather than “nutrition balance”. The parents could be classified into four groups by the quantification theory. It is thought that appropriate guidance to mothers is necessary to improve infants' eating habits from the above-mentioned results.
