My bil has kids who are now 27 and 25. We have two dc too - 16 and 14.
Last year my dh suggested it might be time for us to stop giving to their two, who are both employed and self-sufficient. I mean, when and how should it stop? This was deemed reasonable and they would continue to buy our kids presents, well give money to be exact.
So, that lasted one year and this year, they received nothing.
I feel pretty annoyed tbh - they have benefitted for many more years of presents, which has also included birthdays... anyone else dealt with this with this and feel like me? Or, is that just the way it is?
