My DD age 6 lisps when pronouncing "s" sounds ie "yeth" instead of "yes". I assumed she would grow out of this but she doesn't seem to be. Am mostly concerned that she will get bullied/ the piss taken out of her. Her teacher has not commented on it and otherwise her speech, vocabulary and reading are good. Can we try and help her correct it or should she see a speech therapist? Also - she has gappy teeth, I don't know if this is a factor or not? Any advice would be appreciated :)
