Hi M.,
First of all, pray for your school bus drivers.
I am a bus driver and my kids are great, however they are all still kids, and present many different circumstances to a bus driver, so as I said they need the prayers of the parents.
Hopefully you will get someone who is good with the kids and has the patience of a mommy, but there are ways to get the best help from her driver in any case, and one of the ways is to get to know the driver, such as going to the bus stop with her the first few times, or everytime if that's possible, I know I like to see the mom's there with their kids, it helps all the kids to see parents there, and it helps me to regulate what goes on before I get there, I can seek the help of parents in keeping them out of the street, or whatever may be the particular need.
If a driver knows you are there and willing to participate in the things that go on at the stop that will help to keep the kids more orderly, they need a little extra help at times, and it's just caring to not let them get in the road so that they can get hit, or doing what mommies do that help safegaurd all of the kids.
If there is a bullying problem call both the school and the school bus dispatcher, cause all kids wont tell anyone but you, until they know they have someone they can trust.
It wont take them long to figure out what to do and not do, but she doesn't have to be bullied, she probably won't but still you never know.
Hope her school year will be great.
