Should I change schools

[chelseabuns2013]

My daughters go to a school that they are happy in, have good friends. I becoming increasingly cheesed off with the behaviour of other children, they are too grown up for their age, and generally rough. Primary schools in my area are segregated on religious grounds ( with the nice affluent, articulate kids, middle class parents) sending their kids to c of e schools in semi-rural locations. I'm sick of all these rough types ruining my kids childhood with their poorly brought up kids. Should I move them? I know it may seem like I'm a snob but I just expect no swearing, respectful play and speech and no overtly sexualised behaviour.
