My ds who is almost 8 has always had a bit of a lisp. He does pronounce his "s" and "z" words with a slightly softer sound - maybe not a solid "th" but getting on for it. It's never bothered him or us in any way, it's just how he speaks. However he occasionally when he's saying certain words make that spitting sound that Sylvester the cat makes. You know like when your tongue rolls to make a spitting noise? I'm not sure if I'm describing it well but in my head I can hear the noise but just can't articulate it great! I've only become bothered now because as he gets older I'm worried he'll be teased about it - he hasn't or isn't so maybe I'm panicking over nothing. I've Googled and his kind of lisp is a lateral lisp apparently and is one which shouldn't be left and should be treated? Does anyone have any experience of this type of lisp? And is it something we should see our GP about?
