Does she have any adults she can look up to as Guardians?

[Gokudera wonders why Ken might be feeling pressured. Is it out of sympathy, since he also feels like he should embrace being a child?]

I'm not very good at talking to anyone, so you probably shouldn't take my advice. But... see what she likes, or just ask her questions. Sometimes it's easy to get people to open up if you let them talk about things they like. Like... favorite colors or animals?

As far as independence goes... maybe ask her for her help or opinions on something so she feels like whatever she says plays a contribution?
