My FIL died a few weeks before my DD was born, and I've always felt it was important for her to know her surviving grandparent. I have been taking DD to visit Grandma since she was a baby (she's now 8), as DH can't stand her and wants little to do with her.
I'm now at the stage where I can't stand her: she's lazy, ignorant, prejudiced, nags and hectors my DD, and gives crap, unimaginative gifts for DD's birthday and Xmas.
I'd be happy not to bother going to see her any more, and DD rarely mentions her: should I just give up, as the relationship isn't doing DD any good?
