“But my kid won’t understand what is being said”
Maybe at first, but then they’ll guess. Adults rely so much on language that watching a show in a foreign language is usually painful... But for toddlers, their native tongue IS a foreign language. Do you think a kid really understand every word of Dr Seuss’ books? So hearing French is only going to make things a bit harder, but not impossible for these geniuses that kids are. They have an amazing ability to guess from the context, and are curious about everything... and this is a great help in any language learning.
Be realistic about your goal
Unless you or your husband or your nanny is fluent in French and constantely talks French to your kid, and if you don’t live in a French speaking country, your need to be realistic: your kid is not going to be bilingual.
But that doesn’t mean you cannot “introduce” him/her to a foreign language, and develop his/her interest and ear for that language. This introduction to the sounds and logic of another language will make a huge difference when your kid is old enough to study the said language. I've seen it many times, it does work.
Develop an interest in the French language and the rest will follow
At a young age, the key is to help your child develop an ear and an interest for the French language, not to transform them into the next Voltaire or Sartre. Children at a young age want to show you they understand, and live to please you. If you can show them how happy it makes you when they speak French, it will be the best incentive there is in the whole word.
