over 2 issues.
1 - shaving her legs. She's told me for a couple of years that she is desperate to do it. Now I know she shouldn't have to, but the point is it's her body, her choice. She is really unhappy with her legs (quite dark hair). Her mum said she couldn't do it until she was 13. We were a bit
at this but thought fair enough, maybe she was a bit sad about her growing up etc.
So now DSD is 13 and was all excited about being allowed to shave at last. Her mum refused to buy her any stuff and said she could use her brother's razor
. We realised I had enough spare (unused) stuff for her to use, and phoned her mum to check. She has now said no, DSD has to wait another year. DSD is really upset but is just accepting it. DH (who really doesn't want DSD to shave, but accepts that it is HER choice) has said she can do it here, but DSD just looked sad and said no, she will get in trouble. So she's just going to accept being teased for another year because she's scared of her mum.
- Activity at school.
Last term DSD had signed up to an activity where she would be campaigning for giving up smoking. A big project involving meeting local heroes etc. It was lovely to see her so excited about something as she doesn't enjoy school.
So tonight DH asks her if she's excited about it tomorrow. DSD said no, mum said she's not allowed to do it any more. Not because of having to miss school or anything, but because
"she will rub it in my face because I smoke" 
- on the phone exW was actually gloating about not letting her do it.
DH is livid, as am I. DH has said DSD should do it, she wants to and is devastated. But unless her teacher makes her (because she's committed to it iyswim) then she will simply say "I'm not allowed" and miss out.
DSD has always been very passive, and never naughty barring the odd bit of cheek. We've always counted our blessings that all DH's DCs (they have 3 together) are very well behaved. Unlike the 2 DH and I have together who are challenging to say the least 
But AIBU (DH too) to wish that for once DSD would just think "sod you mum" and do what SHE wants to do? To do what makes her happy?
