Kimberley has trouble saying a few words/letters and has trouble saying f, s and l.

She can't say snake or clock they come out as nake and **** which i am trying to get her to say the right way and i think she can but thinks it's funny.

How many other 4-5yr olds have trouble saying some words or letters.

I'm intrested in knowing this so i can work out what is best to do with her starting pre-primary next year.
