This is just my view but I see others saying same sort of thing OP.
It's you and DP and then her dad and his set up.
She's only little.
She wants and needs to know that you love her. Attention seeking in that situation is understandable I think.
She's been away from you for a few days she wants you to make a fuss of her. Prove that she is unconditionally loved by you and you want her there more than anything.
Pushing boundaries hard is also usual at that age.
The love languages thing is to me a bit odd. Again she's only little. She just wants you. She loves you. She wants to make sure you love her.
And how many rules can there be?
Can't she put her own cream on?
So what if she dances while you're eating. She's 6! She wants you to clap and say nice one. She wants your attention.
I don't think you need to take her to docs or whatever.
Things you could do.
I mean do you ever say like. That's brilliant dancing! Tell you what let's finish eating and then show us your dance so we can see it properly. I can dance with you if you like!
You know, jollying along.
And choices. And explanations.
You need the cream because otherwise that graze could get infected and it'll be painful and harder to make better.
Do you want to put the cream on or shall I do it?
That sort of stuff.
Just my opinion obviously.
