So sorry to hear this roo do you have any professional support, post adoption support etc that you can access.
Good luck. Ask anything you would like or pm me. No, I do not have all or perhaps any of the answers but I have a quirky, slightly difficult birth dd and a new very controlling adopted ds so I also on the journey to get answers!
Yes, I could write this of my birth dd.... "She actually argues that things are not how I say they are even when I have seen them! She says she doesn't like being a child and wants to be a grown up."
She is dyslexic and I think that does affect how kids see the world (ad adults too) they may even feel things happen in a different order to the way others see them.
Your said "We have two dd placed with us nearly two years ago. Our eldest is 6 and I still feel as if I'm struggling to connect with her. She hates not being in control of things and resists being parented. She doesn't want help with reading, anything really, and when you ask her to do or not do something she argues with you."
I wonder if you can build up some time just bonding not parenting, doing stuff like painting or gardening where you are not offering your opinion or being an expert but just doing the stuff together. Have another person looking after little one (if you have a partner or relative etc) and spend that time when you can doing stuff to build connection.
Can I ask (feel free to pm if you prefer) but what parenting advice and help have you had, have you done any parenting courses?
I can really recommend the a Parenting Puzzle as a book and the Family Links Nurturing course as a course, although not designed for adoption situations I did it prior to adoption (trouble with my birth dd, who at the time was 7, now is 9) and when I did the adoption parenting course they used family links stuff. It is all based around empathy,

And yes, I can recognise " She asks for cuddles but then just lays on you in a really awkward way making no attempt to cuddle you back." My dd kept falling into me and I took it as aggression where as now I see she needed to connect but did not know how to.
Please hear me when I say that YES I know it is different for a birth child and an adopted child to exhibit challenging behaviour and there may be different reasons etc and it is not the same! But it is possible that you can learn and develop some ideas from regular parenting books.
Course and books may help. Opt for books that are not routine or rigid, not Supernanny.
Maybe try
'Raising Happy Children' by Jan Parker and Jan Stimpson.
www.amazon.co.uk/Raising-Happy-Children-Every-Parents/dp/0340734647
Plus maybe try How to talk so kids will listen and listen so kids will talk
If you can get some professional advice from post adoption support they may be able to advise you were these books and resources fail and how to top up what is needed or alternatives that are similar but aimed at adoptive parents.
Please do pm me for a chat if you wish to.
Good luck and I think you are right, you need to change how you feel to some degree to make a change, maybe counselling would help you shake off this stuff from the past which is not your fault and free you to be the mum you want to be to the children you have.
