The present study investigated maternal parenting stress trajectories, using data gathered from the Korean Children Panel Survey. Four factors-monthly income, maternal depression levels, infants' negative emotionality, marital conflict-which were taken from reports made by the mothers' used in this study, were examined as predictors of maternal parenting stress trajectories. The effects of maternal parenting stress trajectories, parenting styles and toddlers' peer interruptive behaviors were also examined. The findings were as follows: First, maternal parenting stress trajectories somewhat increased from the 1st year period to the 4th year period. Second, infants' negative emotionality and marital conflict within the first year were observed to have a connection to the initial level and slope of maternal parenting stress trajectories. Third, maternal parenting stress trajectories predicted positive parenting styles, and parenting styles had a longitudinal impact on toddlers' peer interruptive behaviors at the 5th year period.

Objectives: The aim of this study was to investigate the effect of breastfeeding on the occurrence of early childhood caries in Korean infants and toddlers. Methods: Data on oral examinations of infants and toddlers of the National Health Insurance Service were analyzed. The study subjects were children who participated in both the first, second, and third oral examinations and the first general health examination in 2008-2017 (n=142,185). Based on the responses to the questionnaire, the subjects were classified into breastfeeding, formula feeding, and mixed feeding groups. The participants were monitored for the development of early childhood caries in three sequential oral examinations. Results: Based on the oral examination results conducted at 54-65 months old, the decayed-filled teeth index of the breastfeeding group was the highest (2.03±3.08), followed by the mixed (1.96±3.03) and the formula feeding groups (1.82±2.91). The Cox proportional hazard regression model including all the variables showed that the risk of developing dental caries was significantly lower in the formula (hazard ratio [HR], 0.85) and mixed feeding groups (HR, 0.91) than in the breastfeeding group. Conclusions: Breastfeeding children have a higher risk of early childhood caries; therefore, oral hygiene education and regular dental check-ups are necessary.

Purpose: The purpose of this study was to develop a health education program for child care workers of infants, toddlers and preschoolers to improve their care ability. The program provided child care teachers and children with information on how to take care of their health. Method: This program development was based on a systematic design of instruction by Dick & Carey(1996). The process included a review of literature, setting an instructional goal, getting advice from various experts, designing instruction and instructional medias, designing formative evaluation, revising the program and making a summative evaluations. Result: The products of this program were the 'Teachers Guide Book & CD-ROM.' The guide book included health education programs for infants, toddlers and preschoolers. The infant program included a basic baby care program for teachers. The toddlers and preschoolers program included basic health promotion, dental health, nutrition management, communicable disease prevention, substance abuse prevention and a safety program. Conclusion: These programs provided a systematic content of health education for children and their teachers, and useful data which can be applied to child care centers.

The purpose of this study was to investigate the relationship of toddlers' vocabulary ability with reading activities and teachers' verbal and nonverbal behaviors during book reading. The subjects were 52 teachers and 104 toddlers at age 2. Lee and Kim (2004)'s categories of the Teachers' Verbal Behaviors, the categories of the Nonverbal Behavioral Analysis(Kim. 2005), and the Peabody Picture Vocabulary Test-Revised (Kim, et al.1995) were used. The data was analyzed by t-test, ANOVA, and Correlations. The results indicated that there were significant correlations in the subcategories of reading activities in classrooms, teachers' picture book reading behaviors, and toddler's vocabulary ability. The toddler's vocabulary ability increased as the 'interacting time both before and after book reading' became longer. The toddler's vocabulary ability increased as 'connecting with previous experience', 'asking questions for confirmation', 'acknowledging,' and 'expanding' of verbal behavior, as well as the nonverbal behavior, such as 'requesting behavior', 'emotional contact,' and 'empathetic behavior.' In conclusion, teachers' reading behaviors and activities were related to toddlers' vocabulary ability.

In this study, the Infants & Toddlers' Playfulness Scale(ITPS) was developed and its reliability and validity were examined. The participants in this study consisted of 656 parents whose children were 8 to 36 months old. Five factors were identified from the results of the exploratory factor analysis performed on the 29 items that had been derived by analyzing existing research. The Goodness of Fit Indices(GFIs) of the confirmatory factor analyses, performed on the 1st-order 5-factor model and the 2nd-order one factor model, were both satisfactory. Concurrent validity was established by the high correlations of r = .631~.808(p < .01) between each factor of the ITPS and the total score of the Children's Playfulness Scale(CPS), an existing measure for children's playfulness. The reliability of each factor, as measured by Cronbach's ${\alpha}$, ranged from .773 to .883. Consequently, the ITPS developed in this study can be seen as a reliable and valid scale that can be used by parents to measure the playfulness of their infants and toddlers in a multi-dimensional manner.

The present study investigated how mothers with infants and toddlers obtain information about parenting and examined the nature of maternal parenting knowledge in order to evaluate the quality of the information. The mothers' age and educational level were included in the analysis as a influential factor on parenting knowledge. Four hundred and twenty-nine mothers with infants and toddlers completed the questionnaires issued regarding the source and content of parenting information and parenting knowledge. The results indicated that the mothers with only one child preferred to utilize their friends and relatives as their primary source of information and the mothers with more than one child acquired parenting information from their own previous experience. Second, the subjects were most interested in acquiring information related to physical development and medical problems. Third, the main effects of all independent variables were found. In addition, the interactional effects between the educational level and source of parenting information for the mother with only one child and the interactional effects between age and source of parenting information for the mother with more than one child were determined as a result of this study. These results indicate that there are some high-risk groups when it comes to the acquisition of parenting knowledge and we suggest providing valid and reliable information to these most vulnerable groups.

The purpose of this study was to analyze the effects of toddler's temperament and toddler-teacher relationship on their peer interaction, focusing on gender differences. A total of 221 toddlers(122 boys and 99 girls) attending 16 child care centers in South Korea participated in this study. Each toddler was observed during a free-play period in the classroom over 4 sessions of 5 minutes, so a total of 20 minutes was measured. Two observers scored recorded observation scenes with two peer interaction criteria, including interaction initiation and interaction participation level. The main results of this study are as follows: First, there was a signigicant gender difference in peer interaction and toddler's temperament and toddler-teacher relationship. Second, the factor of toddler-teacher relationship significantly predicted the boys' peer interaction, while for the girls, the significant predictor was intentional control of temperamental factors. Further, implications for different approaches according to the gender difference of the affecting factor on toddlers' peer interaction have been discussed.

Purpose: The purpose of this study was to examine the toilet training status (TTS) of Korean toddlers and their mothers' level of knowledge of toilet training (TT) and to identify the relationship between toddlers' TTS and mothers' level of knowledge of TT. Method: The participants in this study were 315 12-29 month old infants and their mothers recruited from outpatient clinics of hospitals and day care centers. T-test, ANOVA and Pearson correlation coefficients were used to analyze the data. Results: TTS of Korean toddlers showed was more advanced compared with previous research samples except for independent hand washing after toileting and this improved with age. The mothers showed higher understanding of the importance of a positive experience and a different pace for each child in the appropriate period for toilet training but less appreciation of the readiness of child to initiate TT. There was a significant correlation between TTS and mothers' level of knowledge of TT. Conclusion: Using the above findings, health professionals who work with children and their families need to develop parent education programs on TT that will promote toddlers' physical and socio-emotional development.

BACKGROUND/OBJECTIVES: Adequate dietary fatty acid intake is important for toddlers between 12-24 months of age, as this is a period of dietary transition in conjunction with rapid growth and development; however, actual fatty acid intake during this period seldom has been explored. This study was conducted to assess the intake status of n-3 and n-6 polyunsaturated fatty acids by toddlers during the 12-24-month period using 2010-2015 Korea National Health and Nutrition Examination Survey data. SUBJECTS/METHODS: Twenty-four-hour dietary recall data of 12-24-month-old toddlers (n = 544) was used to estimate the intakes of ${\alpha}$-linolenic acid (ALA; 18:3n-3), eicosapentaenoic acid (EPA; 20:5n-3), docosahexaenoic acid (DHA; 22:6n-3), linoleic acid (LA; 18:2n-6), and arachidonic acid (AA; 20:4n-6), as well as the major dietary sources of each. The results were compared with the expected intake for exclusively breastfed infants in the first 6 months of life and available dietary recommendations. RESULTS: Mean daily intakes of ALA, EPA, DHA, LA, and AA were 529.9, 22.4, 37.0, 3907.6, and 20.0 mg/day, respectively. Dietary intakes of these fatty acids fell below the expected intake for 0-5-month-old exclusively breastfed infants. In particular, DHA and AA intakes were 4 to 5 times lower. The dietary assessment indicated that the mean intake of essential fatty acids ALA and LA was below the European and the FAO/WHO dietary recommendations, particularly for DHA, which was approximately 30% and 14-16% lower, respectively. The key sources of the essential fatty acids, DHA, and AA were soy (28.2%), fish (97.3%), and animals (53.7%), respectively. CONCLUSIONS: Considering the prevailing view of DHA and AA requirements on early brain development, there remains considerable room for improvement in their intakes in the diets of Korean toddlers. Further studies are warranted to explore how increasing dietary intakes of DHA and AA could benefit brain development during infancy and early childhood.

Objective: This study used a pre-test and post-test quasi-experimental design to evaluate the effectiveness of the Respected Parents & Respected Children parent education program developed for mothers of toddlers. Methods: A total of 40 mothers were assigned to two groups, an intervention group (n = 20) and a waiting group (n = 20). Mothers in the intervention group participated in six weekly sessions of the parent education program. After the termination of the program, differences between the preand post-test in terms of mothers' parenting characteristics (i.e., parenting behaviors, parenting efficacy, and parenting stress) and toddlers' social and emotional characteristics were compared in both groups. Results: Mothers in the intervention group showed significant improvement in their parenting behaviors and parenting efficacy and decreased parenting stress, whereas mothers in the waiting group did not show any significant differences between pre- and post-test scores. Mothers in the intervention group also reported a significant improvement in their toddlers' level of imitation/play. Conclusion: These findings indicate that the Respected Parents & Respected Children parent education program is effective in bringing about positive changes in both mothers' and toddlers' characteristics, which can be crucial for the future developmental outcomes of children.
