While having a parent at home that is fluent in Spanish is a tremendous advantage, you should not be discouraged if you want your children to learn Spanish in a English-speaking only home. Many studies have shown that introducing a second language early in life can help children in many ways.
Katherine Kinzler, associate professor of psychology and human development at Cornell University, has indicated that based on her research, there is good news for parents that speak only one language at home regarding some benefits of exposure to another language. She stated that some of the social benefits, such as being able to understand other people's perspectives better, do not require for the children to become completely bilingual. So even children who have some exposure to another language seem to be just as good at understanding others perspective.
If you speak Spanish fluently or even on a more limited basis try to speak Spanish as much as possible. Your children will be exposed to mostly English outside of the home in most communities. If you do not speak Spanish at all, do your best to expose your child to Spanish at least once per day. This can be done through videos - www.spanishforbabiesandtoddlers.com/spanish-store.html CDs, programming for children on TV (there are several Spanish channels that have shows for children) or interactive Spanish toys.
