Spanish Lesson

I´m getting a good review of the commands while working with the kids at the day care! Mostly used with playground vocabulary
Here´s a list! I can´t find the accent key, though.

¡Subeme! = Get me up! (onto a swing or jungle gym)
¡Bajame! = Get me down!
¡Meceme! = Literally "rock me!" but used as "push me" (on the swing)
¡Empujame! = Push me!
¡Venga! = Come!

Idiomatic expression I´ve heard:
¡Que asco! = Gross!
¡Que te vaya bien! = Loosely translated, That all goes well for you!
¡Nos vemos! = See ya! (Literally, we'll see each other!)
¿Como te va? = How´s it going with you?

The vos form is used here and I think it is a step more formal than tu but not as formal as Usted. All three are pretty confusing. It seems as though you could get away with using Usted most of the time- even with people younger than you.
