Maybe I'm reading it wrong, but it sure sounds like now they have their own biological children and they're not willing to work with her any more?
Well, if they think she had trouble adapting then, she's REALLY going to have issues now. Poor thing!
I wonder what they'll do when their biological kids get to be her age and start whining and being picky about food, too? That's pretty normal as kids' tastes change, etc. I hope they understand what they've done.
Like I said, maybe I'm wrong...I hope so.
