What a horrible thing to say DementedMa.
A family member who is involved in children's tennis coaching has met Judy Murray several times and she is not a torn faced harpy at all, rather the reverse. She found her to be cheerful, professional , positive, personable, and very down to earth. And as Trixy says she does a huge amount for British tennis. Also, you have to do way more than "just give birth" to your dc for them to become elite athletes playing sport at the highest level - you basically give up your own life for them - the selflessness and dedication required is unbelievable.
