Could you please explain the construction of this sentence?

Hi!
- She is always the first one to get up in the morning to make sure that we leave for school having eaten breakfast and dressed in suitable clothes.

Can you explain a little better? I'm not sure what you are asking.

I don't remember who posted this originally some time ago with the exact example, but as Yogi Berra is alleged to have said, "this seems like deja vu all over again".
