It sounds too good to be true, but hear us out. As soon as your children earn some money (yes, baby-sitting counts), set them up with an individual retirement account. Invest what they’ve earned ($1,000 to $5,500 per year) in the IRA until they’re 20 years old. If they contribute $2,000 each year from age 21 on, they could retire with about $1 million.
