This is a genuine AIBU and I have no issues with my MIL, just to be clear :)
She has plenty of money - she could be considered very wealthy in fact.
Her 'hobby' is to trawl boot fairs and charity shops.
My children get a large cardboard box roughly once a month full of stuffed toys, jigsaws, clothes and other random stuff. Their attitude to gifts I think is very much skewed by it - there is so much 'stuff' in their lives that they do not really distinguish between a special day and a random Wednesday - it is a tide of toys that never ends. I've never said anything about it, despite hating how much stuff we have to put into landfill when it turns out a puzzle piece is missing or monthly enforced visits to charity shops to stop our 3 bed semi bursting at the seams.
Yesterdays was different - my 8 year old was
about it and wanted to know why Nana always sends dirty things. Surely I can say something now that the children don't even like it? I genuinely know that she will not understand - she cannot even grasp that I don't have time to pick up the parcels from the post office for a few days sometimes and gets hurt if they don't phone to say thank you the day after postage.
There is a massive difference in the way we see things - I try to buy very little but when I do I invest in something. She likes to shop and is always changing her furniture etc, ebaying things that are a year old.In addition she sees quantity as a joy, whereas I try and buy the kids something really decent, she will buy 10-15 presents for birthdays and Christmas, all of them cheap and will not last - the one time I tried to explain this she said 'oh they just love opening presents, they're not meant to last!! let them play with them for a bit and then throw them away - they're only children for a bit'.
She grew up very poor and talks about having to worry about shoes with holes in etc so for her buying things is her fun, but work full time and it is a burden to deal with all the 'stuff'. I feel like I cannot say anything without telling her she has been annoying for years - which she has. I love her dearly and don't want to hurt her feelings.
Can I say anything?
