There are two types of "lisps," the frontal or interdental lisp and the lateralized lisp.
Embedded Files
FRONTAL LISP (aka INTERDENTAL LISP)
In an interdental lisp (or frontal lisp) the tongue protrudes between the front teeth and the air-flow is directed forwards. The /s/ and /z/ sound like 'th'. The "frontal lisp" is typically considered developmentally appropriate until the age of 7.
The Lateral Lisp
A lateral lisp is never considered developmentally appropriate and a Speech-Language Pathologist should be consulted. A lateral lisp occurs when air escapes over the sides of the tongue. It often sounds “wet” or “slushy” because you can hear the sounds of saliva.

Home Practice
Have your child say quick repetitions of the /t/ sound ("t-t-t-t-t-t-t-t-t-t-t-t"), which anchors those lateral borders of the tongue against their teeth.
Once step 1 is solid, have your child hold the /t/ sound which causes them to inadvertently produce a non-lateralized /s/ sound ("t-t-t-t-t-t-tsssss").
