I haven't spoken to her mother... she has no part in her parenting except supervised contact anymore after a series of abuse.
And who are you to judge a situation where all you know about it is a snipit of info on this thread?
For your information, I cook for, clean for, do 50% of the care for, support emotionally and do every thing else a parent does for her. DP and I have an agreement, we share the care and the responsibilities like any other parents, it works out better for all of us, we make decisions about her together and both discipline her where appropriate. It works for her as she gets stability, a mother figure where she is lacking one, things done for her (dp is rubbish with chores, remembering her lunch for school etc) and she has never once said your not my mum or questioned my place. she and I get on brilliantly (except right now my pregnancy hormones are all over the place). and I find that she respects us equally and treats us the same and that works for us too
so we discuss things together and while we don't always agree we still respect each other's opinions. He feels that when its just me with her then I should do what im comfortable with. She is perfectly happy with the situation and tells people when it comes up that while I'm not mummy I do the mummy stuff for her.
In this particular situation he has the same attitude he often has which is that he sees what I'm saying, that it is bad for her to watch film after film, but just this once won't hurt... only that's every time and he says that regularly for things without realising that these things build up. He can't be bothered with the hassle of getting her to do other things and he's happy if she's watching a film as he can do what he wants undisturbed...
anyway if you have any advice on how to make other things seem attractive to a child who just wants TV then I'd love to hear it, but the anti step mum stuff is not welcome, taring us all with the same brush because the minority stick their nose in inappropriately is not fair at all... Some of us are a main care giver for our step children and do not deserve to be berated for asking for advice on caring for them...
