Start it anyway! If he wants to start his own company, you'll want to be able to support him. If he wants to buy a house, you'll want to be able to support him. If he wants to become a doctor, you'll want to be able to support him.Guess what - it doesn't matter what he wants to do - you'll want to be able to support him, and having that fund will make that easier/possible.
This will probably get a lot of votes here because HN is resolutely anti-formal education, but that's no reason not to have the fund in place in case that's the way the child want to go.
