DD, 4 recently started speech therapy again.

She goes three times a week for 30 minutes and has been for about a month. She has a lot of words but doesn't have all her consonant sounds down.

It is a struggle because she spends at least 10 minutes of the 30 minutes not wanting to talk at all / being shy.
And now we're working on k sounds and she just can't do it. We've tried depressing her tongue, showing her how to make the sounds, singing along to youtube videos... She can't do G or Y sounds either. And this girl is stubborn, if she doesn't want to do it, she won't.

Has anyone else struggled but made it through? Currently struggling? Tips? Help!
