There is not right or wrong answer I am sure, but just because things are are certain way with you and your Mum, doesn't mean it'll follow for your and your daughter. You sound like you are doing a great job.
For me, it was that she never leaned too far one way or the other. I always knew I was loved and safe, but we were never spoilt, or allowed to think we were the centre of the universe. We were special to Mum and Dad, and the immediate family, of course, but not in the grand scheme of things.
I remember a key thing my Mum always said to me when I was a horrid kid... "I don't like you right now, but I will always love you." I can't describe her tone, but it struck a chord with me for sure, in a good way. I knew I could never lose her love and the safety she showed me, but that I had responsibilities within my family, and society in general, and I hadn't lived up to them at that moment (usually by behaving like a general little shit, rather than anything major major!)
Another key thing that worked for me was my Mum standing back and letting me make my own mistakes as I grew. I very rarely saw her cry, not until we lost my Grandmother a few years ago. But in one of our heart-to-hearts recently, she told me she had cried a fair few times, to herself, over seeing me go through things and learn my own way as a young adult. I reassured her she did EXACTLY the right thing for me... let me grow, learn and become an (I hope) rounded person, while still showing me I had her support and love.
She is 100% the Mum I would have liked to have been some day, but I didn't realise that until I was a teenager (probably even later because... you know... hormones and all!)
