Kid songs...

Anyone else get them stuck in their head? My 2yr old loves Dora and has been singing either Arriba- Up, Abajo- down or Abre- open, sierra- close (I know Spanish and English too, I like them both, How about you?) for a while now. I think it's great he's picking up spanish so easily. Heaven knows I can't remember it. Wanna hear something even better, I couldn't remember that second song so I just asked him what open and close is and he told me the words in Spanish. It amazes me. Dh told me Logan was counting the other day in English and Ian piped in to finish in Spanish. If only dh would teach them both more words... English is his first language though and since I don't speak Spanish, I think it's just natural to speak English at home.
