Hi, I would highly recommend Laura Newman, LEAD Approach. She is a speech and language therapist and supports lots of families with children who are struggling. She is holistic in her approach and will be able to help you get to the bottom of the problem.
I am also a speech and language therapist and appreciate this is very difficult at times for parents, even me! Laura has really helped me in just a couple of sessions. The social pressure for iPhones and social media is so strong and this is significantly damaging to children especially girls. I’m not saying that is the reason by any means, but too often I am seeing this in my clinic causing a heap of problems educationally and socially.
The difference Laura’s input has made for me has been so beneficial and I know she would be able to help you as well.
Laura’s website is

You can also contact me at speechtherapysouthlondon.com or speechtherapysurreylondon.com
Best wishes
