Develop a plan of action. How much of a foreign language your toddler learns depends on how much exposure to that language you provide. Decide how much time and how often you will dedicate to learning French. Also, determine what your lessons will entail, whether it is watching videos, singing songs or reading books.
Play nursery rhymes, children's songs and short films geared at preschool-aged children on your computer or laptop. Seek out Internet videos and recordings that present vocabulary in a fun, colorful and engaging way so as best to keep your toddler's attention.
Select French audio versions of your favorite children's songs and play them for your child for set periods of time. Sing along to them to help engage your child's attention. Research has shown that music can help people figure out the cadence of words, or when words start and stop, and the rhythm can help them commit the sound patterns to memory.
Purchase and play for your toddler any one of several proven French educational DVDs. Local libraries may also offer programs for toddlers that involve viewings of some preschool-level foreign language DVDs, such as the Little Pim series or Muzzy.
Read French children's stories to your toddler. Just as a child will pick up vocabulary and diction in his or her primary language, this method also can be applied to foreign language development.
Record yourself reading or reciting a French phrase and allow your child to play it back. Also, record your child speaking in French and let him or her play this back. Children love to hear themselves recorded, and this could also provide endless entertainment for a little one.
Label objects in your house with the French word along with the word in your child's primary language. For example, you might label a wall in your child's bedroom with the French "mur" and the English "wall". As your child begins to develop sight recognition of written words, this will help to reinforce the reading comprehension of the secondary language.
