<prompt> Human: I have 90k from a rental sale that I want to put into 529 plans for my 5 kids ages 14 to 1. This is largely my only college savings so far. My worry is buying in this market; I know trying to time the market is dodgy but if one thinks a correction is due within a couple years, losses would be likely. Should I put part of it in 529 for the younger ones and sit on the cash for my older kids who will need some of it in 4-5 years? Strategy recommendation?  <response>: I know I shouldnt try to time the market, but Im going to try to time the market.
