Out of interest does she stutter in both languages? I find I don't stutter in a foreign language (I can speak French fairly fluently) but that may be as I didn't learn French until I was around 11-12 and have to think about what I am saying. I would be intriguing to see if its an inbuilt thing or something that develops. She is a good age to get some help which is good. Another positive is regardless of her stuttering she can speak two languages. That's pretty cool. Always look at the positives.
