WWJD, eh? Guess I'm not that holy.
Maybe I'm just a hairsplitter, but if I had been struggling to have children of my own, genetically mine, and found that my wife had given birth to the children of a stranger who was not even of my racial group (guess that makes me a racist too), I would absolutely, positively, go berserk.
and six years later? would you still be in a state of berserkness? at this point, they are well into raising these children... (they could have put them up for adoption when it first happened... but they didn't... they chose to keep them... and that is fantastic!.. props to them)... but now to be "worrying" on a daily basis about how the children MIGHT react at some time in the future is USELESS! the only thing all this worrying can do is to actually "make it happen."
they've made major decisions based on rearing these two boys (not trying to have biological children)... obviously they love these boys... now enjoy them... enjoy parenthood... it goes by so quickly...
