At this point we haven't started saving yet, but DS is 2 and #2 hasn't arrived yet. Great-grandma HAS started saving for both. She opened the first savings account within about a week of us announcing our first pregnancy. I imagine when she dies she'll be leaving a chunk of her estate to my kids as well (her only descendents). She and my late grandpa had accounts for my sister and I when we were younger, they're huge believers in higher education.
We will help our kids out how we can, but there's no telling how that may be. There are half a dozen large schools within an hour of our house (both public and private), so it may very well mean free room/board during school. We'll see. We have no intention of paying for their schooling though - if we can we will, but they will not know that until after the fact.
We will also be teaching them that we expect them to get a degree. I don't have one, and DH is working on his right now (in his 40s). We're the first in our families not to get them, and are dealing with the repercussions of it. But, if they need to take a break after HS before going to college, that is totally acceptable. As is pursuing a vocation instead. But they need a plan.
