This is my nephew, Junior, thrilled about getting a new present. He was about to be 3 years old and his English was just as good as his Spanish.

A few months after this video his English improved a lot to make him even more proficient in English than in Spanish (supposedly his mother tongue) and... he changed his accent to American English! though not just yet here (and then they say TV is not such a strong influence on kids)

You can watch more videos by Junior here: Junior, the bilingual boy

THERE YOU GO= Here you are = Here = There = An expression we say when we give something to somebody.

GONNA= (coll.) Going to.

STICK IT OUT= (coll.) Take it out.
In colloquial English we often use the verb STICK meaning "put" or "take", used in a casual way, as when the place itself is not very important.
- Where do I leave this box?
- Oh, just stick it on the table and come here.

LOOK AT THIS/THAT!= An expression of surprise about something you can see (or even something said). Usually positive.

HERE= Again, an expression we say when we give something to somebody.

PICK UP THE PHONE= Notice the phrasal “pick up” used to talk about the phone. The opposite is to put it down or hang it up.

TRUCK (AmE)= Lorry (BrE)

Opie= /oupi:, əʊpi:/ An expression Junior just made up right then (or maybe he picked from TV?). Apparently he meant “open”, in a kiddy-fun way, that's why it makes sense to say "let's opie-opie" (= let's open it). This is another proof that Junior is not only picking up the language, but also the creativity and flexibility connected to that new language.

THAT’S FINE= It’s ok, don’t worry, no problem.
