how do I make this fair?

[maat55]

I have 8 brothers and sisters. I started the tradition when my oldest sister had her first kid, all of us kids + mom and dad - the one having the kid would put in $25 to go towards the child's future. Someone would generally give a bit more, so we had an even $250 to give, and the parent would either put it in a savings bond or start a mutual fund for the child. I know $25 a person isn't much, but when we started, most of my brothers and sisters were still in high school/grade school, so we just started with $25.

DH's SIL is now pregnant. There is only 2 kids in their family (DH and BIL). Should I try to find a way to carve $250 out of our budget for my upcoming nephew?

Or is this a case of "it doesn't have to be fair"?

I don't believe in tit for tat. Do what you want and don't worry about it. You may be doing the rest a favor by stopping the snowball.
