Can children be "seductive?"

Other than the language peeve as already pointed out by JD: yes.

How should an adult handle it?

I don't think there is a universal answer to that. It depends on many things: her age (and gender,) what your relationship is, among others.



For instance, I think you overreacted to both instances.

The more proportionate one was the latter one. I think you overreacted, but essentially there isn't much margin there. You panicked. I would have tried to be calm. But the outcome I would have aimed at would also be to lead her back to her room so she went on, without me. The former one is, I think, a complete overreaction. By and large, children prefer nakedness to wearing clothing. Acceptance of clothing is one of the single largest battles that parents have to fight for acculturation. She just wanted to try to be naked for a while, not to seduce you. If she had wanted to seduce you, she wouldn't have waited for you in bed, but gone for you wherever you were, as the other girl did. In that situation I would certainly have told her to pick up her clothes; and would probably have given her a talk about acculturation regarding the nudity/clothing dichotomy. But it's likely I would have still allowed her to be naked all day, even if I had to work and be unable to sight the beautiful views.
