Bonjour Isabelle,
I started to write in French, then decided that might be a bit rude for everyone else. We are from Ottawa, so not that far away. We have two kids, my daughter will have just turned 5 and my son will almost be 2. Unfortunately, while I understand French and can speak passably (I work in Gatineau for the federal government, so I get by), my husband doesn't speak a lick (he grew up in Florida and knows more Spanish). My daughter is in her first year of school and does one week of English followed by a week of French, so she does have a tiny bit - she'll be able to sing "Tete, epaules, genoux, orteilles" with your kids, and sing songs about the days of the week. While not really set for conversation, she might be able to say a few familiar words. It would probably be a good learning experience for her to actually speak with other French children, though.
Welcome, and it will be exciting to have someone from close to home onboard!
Sandi
