My six-year-old son needs speech therapy.
The diagnosis is firstly a myofunctional disorder with a lack of lip closure, impaired orofacial sensitivity and coordination, non-physiological tongue rest position and hypotonicity of the orofacial and tongue muscles. Secondly, an articulation disorder with partial dyslalia.
Exercises are comprised of various tongue movements, loud tongue clicks, use of straws.
He has been attending therapy once a week for 2 years, but has not practised with us at home for many months (the therapist says, this is crucial for progress). Progress has stalled. I have tried to introduce playful elements, I have offered a reward for regular practice - nothing works more than once or twice. He completely boycotts our exercises at home, either he is completely passive, he makes nonsense or he is accusatory ("I don't want any more speech therapy. You can't control me.") Our son will start school this year. He is quite smart and interested. I am very worried about his articulation problems in the school context.
How can I help my son and practice successfully with him at home?
