SILs rude child

[Purplelamp87]

I really need to vent about this. We saw my SIL and her 8 year old daughter over the weekend and I've come back absolutely exhausted from the rudeness. It was constant, aimed at both her Mum, me and my DS and was basically ignored.

AIBU to think she is going to really struggle as she gets older?

Examples include:

• saying 'disgusting' to the slice she chose and I paid for and it didn't taste like she expected
• told me 'i had no idea what I was doing' when putting my DSs carseat in. This was a continued commentary on my uselessness while I put it in
• said she didn't like any of DSs toys right to his face and really upset him
• after visit to the cinema said she didn't even enjoy it so I should buy her sweets because that's what she really wanted

AIBU - she will get worse

YABU - it's a phase

I've found on MN there is a school of thought that it is the height of rudeness for a non-related aunt/uncle to get involved at all. Which I don't agree with, and I think it's fair for you to prevent an older child from setting a bad example to your own child, in this sort of situation.

But, could your DH (or your sibling) have a word? It might come better if it was raised between siblings rather than sisters-in-law?

Ignore or tell her "this is unkind/ not nice"
