geting changed at school

[Angeliz]

Hi all.
My eldest dd (8) is just getting to the point at home where she'll get her own sopace to change. She doesn't mind me at all but will shy away a bit from dp.
At school she told me that on one of her p.e days they all change together in the class (boys, girls and male teacher present) and that the girls crouch down behing the chairs.
I spoke to the teacher and they moved the girls to an art area of another class but dd informs me they now are having to change with the year 3's and the boys from that class.
Now i know she's little and there's nothing to see but this is about her feelings and modesty so dp is going to e-mail the head today.
Where do your 8-9 year olds change in school?
(School HAS a changing room but is being used by the senior school that morning!

DS2 age 7 gets changed separate from the girls. DS1 age 9 certainly would not want to get changed in front of girls and is very worried about privacy.

All primary kids here (Australia) wear their PE/sports uniform to school if they're doing PE or sport. I love it - deals with the issues of the practicalities of changing, losing uniform etc. for younger kids and privacy issues for the bigger ones.

I know it may sound prudish but my DS is only 5 and half and I hate the fact that he changes for PE with the girls. I don't like moving the goal posts so to speak and although the children in his class are miles off development I don't agree with telling them it's fine for the x number of years, then the next minute saying it's not.
Since starting school he has developed problems pooing himself at school, clean the whole 7 weeks of the summer hols then started again 2nd day back at school, they of course are insistant there could not be anything at school causing it, surprise surprise. But that alone makes me hesitant of his changing with no privacy, as the school don't always notice and can leave him hours before noticing (smetimes it's so dried on when I get him home that his poor bottom bleeds if you try to use wet wipes).
Maybe that influences my feelings somewhat but I do believe in consistency of rules and acceptable behaviour.
