I would agree with all of StarBright's post, and I also plan on helping my kids with matching their savings, etc.
I would say I'm a recipient of "EOC". I received substantial help with a house down-payment, paying for (cheap in-state) college, funds that kick-started my retirement savings, and an on-going annual gift. I tend to count on the gift in the future, and it makes me less motivated to earn.
But then, enter the MMM mindset-
I'm not more motivated to spend. My annual gift goes straight into an IRA. I view the gift as another layer of financial protection, which has comforted me enough for my wife to be a stay-at-home parent, and for me to be a part-time stay-at-home parent. My salary pays the bills, the gift goes into savings. If things were to go dire (probably only medical would do that), then I could use the gift on that.
These financial gifts have made all the difference in my family's life, and I would do the same to my kids. However, I have a sibling who has also received a yearly gift, and I would say it gets spent, and more relied upon as a crutch. If I don't trust my kids' abilities to manage money, then I will have to tread carefully before giving them too much, too soon.
