Your accent will not damage your child's French

Children calibrate their pronunciation to the input they get most of and the input that comes from native sources. A child who hears native French, from audio, from school, from media, from anyone fluent, and also hears their parent's imperfect French does not end up with the parent's accent. What they end up with is a parent who talks to them in French.

Here's the liberating maths: a parent who says it slightly wrong, warmly, five times a day, gives their child thousands of moments of French a year. Every imperfect sentence counts in full. The scripts and audio exist so that un versus une never has to hold you back again.

Seven sounds are worth ten minutes

Not for your sake, for comprehension. These seven change meaning, and getting them roughly right means your child understands you the first time.
