Welcome to BE.
Re your question, you could try contacting Ruth, BE's child psychologist, as she may have some advice for you. It's a free service if she answers your query in her regular BE column. (Just like a magazine problem page.) It's confidential too. If you decide to do this you can contact Ruth directly via her contact form on BE.
Here's a link to Ruth on BE:
Please check the archives first, though. There are links to them near the bottom of the page I referred to above. The question may well have already been covered in her columns.
Hope this helps.
