See russian fudge and UC there was none of that about dsds mum when me and dp got together- there was clear problems going on by then so as ss were involved and a court case had been booked around the time we got together, I knew what she was like.
Big pig, I'm quite lucky actually, I do get to make decisions about her care and upbringing, with dp of course. He treats me as another parent- which I think is fair, I do cleaning for the household, look after dsd 50% of the time, doing lots of the things she needs doing and he gets to share responsibilities. So I am able to tell her off as I feel necessary (he knows I wouldn't do anything he wouldn't), decide what treats she gets, go with him to important meetings like parents evening, take her to appointments if he's not available. Any big decisions we discuss together as he values my opinions.
Her mother doesn't take part in these decisions- when she had her, she didn't consult dp on anything and now she doesn't make any attempt to be a part of these decisions, she doesn't even do any of her homework with her when she has contact (visits her at her grandads), leaving us to do it all on one night. At a ss meeting she said she was worried she would loose touch with her academic progress- she was told by the teacher that she could arrange a meeting with the teacher at any time, but according to the teacher she has not done so since dsd came to live with us. She does not ask about doctors appointments or progression with anything, her father is the go between but he never asks about these things. Occasionally, we might pass on some info to the grandad as we feel it should be shared but other than that there are no questions. Dsd has ld and is not able to give an accurate account of these things so it's not like she hears it all from her.
My other 2 dsds live with their mother and dp doesn't really get much in put. She restricts access (its easter holidays for the next 3 weeks- dps mum asked if we could have them for one of the weeks and apparently she said 'but I've taken the holidays off work specially" when dps mum pushed she said she'd let us know, but hasn't. She does have 2 other children and 4 step children of her own to spend this time off with... it seems unfair to deny us one week, or even half the week!) But then they are more able to tell us what is going on in their lives, not that dp gets to make any choices or is ever asked what he thinks. One of them is unhappy their due to the step kids bullying her, we tried to discuss calmly the possibility of her living with us, as she had specifically asked several times, but her mum guilt tripped her, saying she'd be devastated and has several arguments on the phone with dp and the result has been that she refuses to listen to dsds feelings and dsd now doesn't want to talk about home at all, we have since asked if she is still unhappy and she changed the subject...
So yes a big contrast between the 2 situations!
