Infinitives after "que"

Question

I feel like I am misunderstanding something here, from a song:

Poco después vino un niño,

Que no sabe de otra cosa

Que corretear por el campo

Y que ver las mariposas.

~~~~~~

A little while after, came a child

who didn't know about the other thing (referencing the butterfly in the song)

that ???runs/travels??? throughout the countryside

and sees the butterflies.

////////

1: What does "corretear" mean here?

2: Why aren't "corretear" and "ver" conjugated? After "que," shouldn't the verb be conjugated in these situations?

3: How do I tell which the 2nd "que" phrases modify: the "boy" or the "other thing"? I feel the the boy is probably seeing the butterfly, but is the boy or the butterfly the thing that is going through the country?

Gracias de antemano.

Answer 1

...vino un niño que no sabe de otra cosa que corretear por el campo y (que) ver las mariposas.

Almost literally:

...came a child that knows no other thing [other] than running throughout the countryside and [other than] seeing the butterflies.

I know. I wrote "than" first, but I was trying to be so literal, that I changed it in the end. - lazarus1907, Mar 24, 2011

Answer 2

It's the same in English:

who knows nothing but to run through the fields looking at butterflies.

Although in a non-poetic setting, you would use "knew" to match the previous tense.

I understood it totally wrong, then. Gracias! - Luciente, Mar 24, 2011
