Ds2 - a delightful 3yo with v good speech and vocabulary can't say 'sh' or 'ch'. Is this normal? He has an Adam Clayton-esque lisp which adds to his natural charm but I'm wondering if this adds to the inability to make a 'sh' sound. Words like 'lunch' or 'finished' sort of come out of his nose (quite a hard sound to describe - something akin to make a pig-like snort from nose and back of throat - between that a the Scottish 'ch' sound at the end of 'loch'). No real desire to send him off to a speech therapist but wondered if we leave it too late is he going to curse us as an adult with a weird (rather than endearing) way of saying things?
