For the first couple years after our son was born, we put about $10k/year in his 529. Relatives have contributed at little over the years, as well. The funds are invested conservatively. We have about 2 years of college in there now (he’s 12). I’m a fan of getting a 529 started, if you have a bit of cash. It wasn’t on my list of urgent things at the time. However, now I’m glad we have something there. Even if we don’t add,it’s a good start that provides options.
