DH has 2 older girls and we have 2 DC. There is a 10 year gap between DS and DD but only 3 years between DS and DSD2. When the DSD's were younger PIL took them to Canada but not DS because we couldn't afford it (XW paid nothing). Now that DS is turning 18, my dad has offered to buy him a car.
This has opened a can of worms with DSD's because he would be getting a car when they didn't. However, DSD2 was added to BIL insurance when she passed her test and DSD1 is only starting to learn.All 3 were offered the opportunity to save towards their 1st car and insurance and we would match their savings, but the only child who did that was DS because he saved all of his birthday and Xmas money. Would I be AIBU to point out to them that his Grandad paying for the car is the same as when their GPs paid for them to go on holiday but not DS?
