So happy for you all that it went smoother than everyone thought. There will be bumps along the way and you will work through them together, you have been great at handling all the different bumps so far 
As for DSD's emotional reaction in the evening, I think most kids of her age, regardless of if it is the expecting of a new baby in a "necular, non-blended" family, or if that baby is on one side of the "blended" family, will go through the emotional highs and lows of wondering how the baby will change their place in the family. Those of us with the uniqueness of blended families just have to remember that our kids may have a bit more adjusting to deal with, and also have more "ammo" to throw at us when they are upset. Just like my brother and I did during rough times, my parents are still married (39 years) but my brother and I are adopted (both at 6 weeks old, so no major traumas in our past or anything) but I think we both (brother more than once) pulled the "You're not my real mom/dad. She/He would let me do that/love me more/whatever drama is going through their heads.
