Community-based cross-sectional study was done from September 9 to September 28, 2017 in Faggeta lekoma district, Amhara region, Ethiopia. The district has 27 kebeles (25 rural and 2 urban kebeles).This study was done among 6 kebeles of the district. The study population was all mothers who have children aged 6-23 months living in the study area for at least 6 months. Only One mother who was unable to speak (with problem of speaking) was excluded. Sample size was determined both using single population proportion formula ([n=[(Za/2)*P(1-P)]/d) and by considering the predictor variable (table 1).

The higher sample size which is 288 was taken. By considering design effect of 2 and 5% for non response a final sample size of 605 was considered. After proportionally allocation of the expected sample size in to the selected 6 kebeles, study subjects were selected by simple random sampling method by using lists from the health post registration book.
Data collection methods and quality assurance procedures
Data were collected using pretested, structured interviewer administered questionnaire. Pretest was done on 5% of mothers. For the data collection five diploma nurses as data collectors and 2 BSc nurses as supervisors were recruited. Two days training was given to data collectors and supervisors. To measure the feeding frequency and dietary diversity 24 hour food intake recall method was used.
Complementary feeding practice indicators
Timely introduction of complementary feeding: children 6-23 months of age who started complementary foods at 6 month (16).
Minimum dietary diversity: children 6–23 months of age who receive foods from four or more food groups during the previous day. The seven food groups are: grains, roots and tubers; legumes and nuts; dairy products (milk, yogurt, cheese); flesh foods (meat, chicken and liver/organ meats); eggs; vitamin A rich fruits and vegetables; and other fruits and vegetables (16).
Minimum meal frequency: children 6–23 months of age who receive solid, semi-solid or soft foods the minimum number of times or more (minimum is defined as: two times for breastfed infants 6–8 months; three times for breastfed children 9–23 months; and four times for non-breastfed children 6–23 months) in the previous day(16).
Appropriate Complementary Feeding Practices: if the mother responds correctly all the above three indicators (if initiated Timely, fed Minimum dietary diversity and gave Minimum meal frequency) (17, 18).
Data management and analysis
Data were coded and entered into Epi-info version 3.5.1 and exported into statistical package for social sciences (SPSS) Version 21.0 software for analyses.To identify factors associated with appropriate complementary feeding practice, first a bivariable logistic regression was performed. Those significant variables in the bivariable analysis (p-value < 0.2) were incorporated into the multivariable logistic regression.
