It's never too early to start. There is so much to know. I started contemplating whether or not to homeschool at about the time my son was 6 mo old and now he is 19 mos. I still have a lot more to learn but I am at least going in a particular direction. Find out what other h/s groups are out in your area, get to know them, if you find out you don't really have any, you may need to think of forming your own little informal group, read, read, read, there is so much material out there, either on the internet or books, John Holt is a good author about Unschooling, research cirriculums to follow if you choose not to go the unschooling route, build your support network. Good luck!
