Speak to your child in the foreign language as early as possible in his development. If the aim is for the child to become bilingual, use both languages when talking to the child right from birth. One parent may always interact with the child in English, while the other speaks to him in the foreign language, or you may choose to speak in different languages at different times of the day. Develop a system for which language you will speak when, and stick to it consistently.
Watch television programs with your child in the foreign language. Some movies are available with audio tracks in multiple languages, so consider watching a DVD with your child in English one day and in the target language the following day. This is a fun and enjoyable way for your child to learn, and she will absorb new grammar and vocabulary subconsciously.
Use picture books to learn new vocabulary. Point to the picture of the word you want to teach and say it aloud in the target language. Choose a book that is suitable for young children and focus on teaching words that they are already familiar with in English. Reinforce the learning by using the same words in context when speaking to your child in the following days.
Sing songs to your child in the foreign language. Even at a very young age, children are capable of acquiring new language based on the sounds they hear around them, and the earlier your child is exposed to the foreign language, the better his language skills are likely to be. If you are not confident in the language yourself, buy a CD of children's songs in the language and let your child listen to it while playing around the home.
Encourage your child to speak in the foreign language. Praise your child when she makes efforts to speak in the language, and try not to be concerned if she sometimes mixes languages, as this is common in the initial phases of learning. Introduce your child to other environments where the target language is spoken, for example by socializing with other children who speak the language or visiting the country of origin.
