Hey Berry!

I think prem kids are amazing little beings, don't you? Like you said your daughter is perceptive and strong and I think you are right, it does stem from what she went through at birth. Personally, I think you sound as though you already concentrate on the positives of your gorgeous girl. Both from a prem perspective and from the pride you have for your daughter. It's ok, I think to relate to prematurity the way you are - that she had a shakey (sp?) start but she has done AMAZING things since her birth. Look at everything she has overcome! That IS taking the positive out of the prematurity.
I don't think you need to play down her early arrival, I think you should continue celebrating who she is because of it!
