tootsietoo - no probs. To be fair, if your/any child does genuinely have a personality disorder, owning that label and using it to find the right way to understand that child's world so they can engage with those around them is hugely important. I'm just always a bit wary of throwing pop diagnoses around - once we start labelling someone that way, it can be really easy to read their future behaviour in light of that label, so it becomes something of a self-fulfilling prophecy.
I agree that being unable to touch her after she was born must have been difficult for both of you, and may have affected your bond (on both sides, really, it's amazing what we can bury that way).
The more you can build routines for her, the better of she'll be. But I understand that's not always possible with kids!
I'd consider getting her to see a professional if her behaviour problems are causing her great difficulties at school or if you really can't cope. But I would be wary of getting a diagnosis at this early an age - several reasons for this, one is that it's far too easy to be misdiagnosed and then it becomes hard to shift that diagnosis later (which is why personality disorder generally won't be diagnosed by a professional until the individual is 16 or 18 in most countries), and partly because if it is causing her problems at school you might just find those problems get worse if she gets labelled by classmates in this way (if the visit to a psychiatrist/psychologist is disclosed to them by anyone).
I'd recommend reading a book called The Chimp Paradox. I think it might really help you both (her behaviour, and you in coping with it and keeping your energy levels up). It's by a guy called Dr Steve Peters. I suggest this because it's a great book for managing emotional outbursts generally (all of us can benefit from it), but also because each chapter has some little exercises in it that you can both do together. While it's aimed at adults, the concepts he uses to describe how we act involved kid-friendly things like Chimp, Gremlins, and Goblins, so you could explain it to her and work through the exercises together, and it won't feel like some dry academic thing at all. It's really easy to read for adults, and kids will enjoy the characters he uses.
I hope this helps.
p.s. psychiatrist/psychologist - the main difference is that the former can prescribe drugs while the latter can't. It's more a difference in job description than what they know or what experience they draw from. ;)
