It's the unfair difference in treatment between the OP and her sister that is pissing me off. If the OP's mum is only going to do a dash and run when the OP's sister's baby is born, then go and see the OP's DC's, then fair enough.
But I can't see that happening, can you?
And THAT'S what I find unfair on the OP. Her DC's don't matter as much as her sister's, from before her sister's DC was even conceived.
And that WILL be bloody hurtful. You look at your wonderful DC's, and can't understand why they aren't equally as important as your sibling's DC's. Of course the OP is going to be hurt by that, both for herself AND on her DC's behalf. I can't understand how people can fail to see that, and are telling her she's wrong to feel hurt by that, and should just ignore that.
Why does the OP's upset at her DC's being less important to their own GM matter less (as she is being told she is wrong to feel like that) than her sister's upset through infertility.
There is no difference in the hurt between suffering infertility, and a family member dismissing your DC's as less important than your sibling's DC 's. it brings out the Mama Bear in you, wanting to protect your DC's from feeling 'second best'.
How many threads on here have we seen where one sibling's DC's are treated like the Golden GC, and the others not bothered with? And the general consensus on those threads is that you have to distance yourselves and your DC's from that sort of unequal treatment, as it is quite insidious and damaging. Which it is.
Yet because her sister has suffered from infertility, the OP is meant to ignore her (what looks to be very real) concerns that this might happen to her own DC 's?
THAT is the bit I don't get! So even if her DC's get to 2/3/4 or older, and notice that their cousin is treated differently by Granny, the OP should suck it up and ignore the effects of that on her own DC's, because her sister suffered infertility?
Maybe I'm wrong, and the OP's sister suffering from infertility SHOULD mean that the OP and her family get sidelined for years by her parents, I just can't see how that is right, when the OP's parents could have handled it so much better, by giving BOTH sisters the support they needed.
