My kids and I are not bilingual. My husband is and the town we live in is on the Mexico border. My daughter will want to watch her cartoons in Spanish sometimes, my son never does. Some families want to raise their children with Spanish as their primary language. They speak only Spanish in the home and watch only Spanish language tv and the kids learn English from cousins and at school. Most people in town use Spanglish, which is not very good English, and they say it's not very good Spanish either. I wouldn't know. So my household is on a different path to bilingualism than yours since no one speaks a lot of Spanish directly to my kids. My kids have heard a ton of Spanish every day of their lives but haven't absorbed it by osmosis.
I have an American Spanish grammer program. It's a third grade level. I seem to remember studying Spanish in third grade when I was in school. I guess that's when they teach your first foreign language. I plan to teach my kids two years of English grammer and then introduce Spanish when I teach the third year of English. My husband is fully bilingual and has lived here his whole life and can not read Spanish.
They do watch stuff sometimes like Pocoyo, Dora, and La Casa De Mickey (mouse). After they learn their Spanish grammer I also bought a region free dvd player and tons of Disney movies in Chinese. (for around the same price as the Rosetta Stone program would have cost). No one's here to teach them Chinese but I assume learning languages is like anything else and it gets easier the more you do it. So they'll at least have native-like exposure to Chinese and language arts lessons in English and Spanish. Since I live here I remember how the phrases sound so when I read Spanish I sound convincing, just with minimal comprehension.
