still says W instead of R at 4 and a half - is he another Jonathan Woss?

Just wondering if I should be doing something about it as I saw a poster which said that speech therapy is more effective before 5.
I was being a little slack and assuming he'll grow out of it but unfortunately he has a R sound in his name and so does his brother so it's quite obvious, and people have started mimicing him.

I have an Irish work colleague who still says 'th' as 't' most of the time. People find it funny, especially when she says 'third'.

Just imagine when I start talking of my teeth... so embarrasing I just try not to use the word anymore
