Bonjour et bienvenue. Your french will sound much different than mine, which is Acadian-influenced "scholarly" Canadian french. ;)
I'm not a francophone, just bilingual... so I haven't just naturally spoken french at home around my kids like I'd hoped I would. Having to teach them par exprès instead. But at least they're learning.
12yo DS was slow to be interested, and even though we 'started' french when he was quite young, nothing and I mean NOTHING stuck until the past couple of years, where he's finally applying himself. He can now read basic french readers -- like simple K-level kids' books -- independently, and his pronounciation is really quite good. It's now mostly a matter of building vocabulary, syntax, and fluency.
DD4 is much more keen. So far she loves to ask "Comment t'appelles-tu?" and answer "Je m'appelle..." when she's asked. She knows bonjour, bonne nuit, au revoir, je t'aime and je t'aime aussi... We're using Nallenart's "L'art de dire" as a guide for now, I'm trying to be a little more consistent with her since she is interested. :)
