I think this is a good example of the media taking statements out of context, misconstruing what she probably meant.
I think she was trying to go out of her way to show that she is just as attached to her adoptive children as her natural one.
When the baby first comes out it takes a while to bond, form that close attachment. Takes awhile to form a personality. (Take it from me, mine screamed for 3 months; it's difficult)
When you see a child in an orphanage, without parents, there might be a more immediate emotion there.
The entertainment mags are dying for a star to say something ambiguous so they can take it and run.... and they do.
That's why most of the stars, if you look at what they say now to interviewers - it usually means absolutely nothing.
