I was on here years ago, trying to get MIL's thinking interpreted by the hive mind.
That Christmas DD1, aged four, received a generous amount of well thought out bits.
DD2, aged 2, received a TV tie in book, for something we didn't have access to from a charity shop with the previous owners teeth marks.
Apparently, this was to match the other grandchildren a 3 and a 1.year old who we rarely met up with. The thinking being the one year old wouldn't mind.
It's got worse over the years, but I rarely find out the logic now. We get cooked a tiny, mean curry, the others get meals out, holidays, pocket money, fuel, jewellery, cakes and half a dozen pasties.
Any visit is bookended and constrained by SIL & BIL's families, their childcare needs, gifts shopped for locally, it's bonkers. Took me years to see properly.
The kids are 18 and 20 now, so I feel no need to put a positive spin on that branch of the family.
It was £25 for the 18th birthday. They spent more on pasties for BIL's family.
