The purpose of this study is to investigate the perceptions of parents about the relationship between speech production and the usage of pacifiers and thumb sucking. One hundred and twenty five participants with children below the age of ten completed a digital questionnaire sent out through social media. The results revealed that the parents who let their child use a pacifier or suck their thumb use a variety of sources to gain information and form opinions about this. These ranged from print materials to website to friends and family. Pacifier use was more frequent than thumb sucking. Most parents did not report speech difficulties in their children and few of those who did, associated these with pacifier use or thumb sucking.
