You may or may not be aware of this, but my maiden name is Meza. My family is from Costa Rica and that makes me one proud Tica! I'm working on teaching my children Spanish but it's coming slowly. I know for sure that they understand "besito" (kiss).
Funny. That was the first word their father learned too. ;)
Here's a video of the twins enjoying one of their favorite nursery rhymes! Enjoy!
