I am waiting for speech therapy appointment for DS (5), his overall speech is a bit unclear (although mostly understandable) and he has particular trouble with th,f,v and l(l in the middle of words, like "easily" said as "easiylly"). He tries, but he physically can't seem to get his tongue and lips into the right positions. I try and get him to watch my mouth making these sounds, but he finds it hard to copy, he also can't make a proper circle with his mouth to blow candles out etc. Has anyone had similar experience? I am starting to wonder if he needs something like cranial osteopathy to release things, or are there particular tricks to try and teach them how to achieve the positions with their mouths? Thank you.
