I am very curious to know about why parents use pacifiers. I come from a country where use of pacifiers is NOT the norm. In fact mothers are often discouraged from using them in my culture. In my country breast feeding is an absolute norm and mothers are instructed to breastfeed exclusively (since there is compulsory maternity leave for 4 months), and mothers usually breastfeed for a year minimum. I've never actually seen a baby with a pacifier back home. After I came to the US I see lots of babies with pacifiers...why do you use them? Is it to stop babies crying? does it ever cause crooked teeth or overbite?
