My MIL is absolutely obsessed with how advanced DD is - I take much the same approach as Indith.
We was here at the weekend..."I do hope she'll be bright" (she's 8 months old)-WTF?!
I did try to point out that being bright wasn't everything and we'll be very happy if she grows up to be a well rounded, happy little girl who's nice to everyone incl. small animals.
"Hmmmmm" says the MIL, in atone which indictaes she blatantly doesn't agree, "but we still want her to be bright"
Every child she talks about is referenced in terms of how bright they are........why?
