I have always frowned on the use of dummies, because my mother (who ran a nursery for 25 years) was adamant that they can hinder a child's speech development.
Our new baby is very unsettled and very collicy, and the midwife is recommending using a dummy to help settle him.
So, is there any evidence behind this claim that it hinders speech development? And if so, what is the age that it starts making a difference?
