If it's possible, see if you can help in the classroom one day a week. This will move her social standing to the cool kid, & you the cool mom. The biggest reason, is so you can see what the other girls are about and help guide her friendships. This will only work for a couple more years, so take advantage of this time. We have had to move several times over the years, and this always-without fail-works like a charm!
