help!

This is not a well-written sentence (it contains mistakes) but it means the child has a great affinity for (a considerable talent for) dancing.

Simply put, the child loves dancing, and is good at it.

"Help me" is not a good topic title.

The subject should be relevant to the topic or question.

Ideally the subject line should be able to summarize the question.

Using a relevant title will greatly increase the chances of an answer.

An example of a bad title is: "HELP ME!"

An example of a good title is: "How do I reinstall Windows XP?"

Using all caps and screaming for help will usually mean most people ignore you.

If you use a relevant title with relevant keywords more people will find your topic.

Thank you for your co-operation

It also implies that she was born with it; hence the use of the words "genes" "blood" and "bones".
