First of all we would like to thank the authors for their concern and their comments to which, we will respond below:
Guney and Zagury commented:
Study design concerns
Sample size: As a broad consumer product category, essential childcare products cannot be reduced to two product categories: teethers and teats. Also, this category cannot be adequately represented by the very limited sample size tested in the study (n = 5). Therefore, it is not possible to reach general conclusions or to make research recommendations for essential childcare products solely based on the results of this limited study.
As mentioned in the paper, the age group chosen for this study was 6–12 months old; therefore, the word essential is the most appropriate word for these two products because the children need them day and night. The word essential describes the importance of these products in children’s life and does not mean we reduced this category to these two products (simple understanding of...
