Whenever I meet someone NEW to homeschooling, the first piece of advice I offer them is to find a homeschool group that WORKS for them!
Whether it is a religious group, a pagan group, a secular group or whatever....find someone or a bunch of someones to bounce ideas off of, get info from, and vent to! Because you will need to do all that and MORE!
Me personally, I joined a secular homeschool support group both online AND in my area and it pretty much saved my sanity!! When both my boys had issues with high school writing, where did I turn but to my secular forum! I was able to post my question and had TONS of support and new answers and was able to see things in a new light and work through it!
We also have a great local group of kids that my boys have grown up with the past few years! They each have a few friends and we do many, MANY things as a group. Again, saved my sanity and between us.....we learn about lots of local things offered that our kids can do together!
People ask about curriculum, what we do for socialization, etc. as their first few tips when starting to homeschool but I always tell people to find a group!!
