I see no one wants to answer you. People bring kids, babies and dogs. Do I agree with it, not necessarily the babies and kids are at your own risk.
This is a typical music festival. Lots of drinking, bad language, skimpy clothing etc. During the day it isn't so bad but when the sun starts setting, the things get wilder.
You can certainly judge where you are sitting the first evening and if it doesn't fit, you can move. There is a tent set up on the hill where alot of the older people sit and people with younger children. It is further away from the stage but tends to be a quieter crowd.
