Aside from Bahay Kubo, what are good first Filipino songs to teach my child?

You can try the ever-classical Filipino song "Paa, Tuhod, Balikat, Ulo" (tagalog version of "My Toes, My Knees.." and please don't forget the choreo! ;) Not only the child will learn the famous song, but also will try to learn her parts of the body ;)
