Thats great news! I love hearing stuff like this! You should be proud of her and you rightly are. She can't be a winner all the time. I love martial arts...my boy has been doing taekwondo now for 18 months and is a red belt (the belts are different to Karate) He's only 5! He's been doing Judo since he could walk (taught by me) and he started officially with a club on his 5th birthday. Walked in and threw all the other kids for Tai-otoshi! (little bit of extra coaching from dad helped there). He fuckin loves it! He regularly beats up 7 year olds but cannot compete until he gets to 8 himself.
I did teach him a couple of chokes and armbars but got in trouble with the wife for that

Keep it up and give her all the encouragement she needs. Well done to her!
