Hi A.,
I've been homeschooling for 6 years now and am a Mom of 4 also! My youngest is 6 weeks and my oldest is almost 12. I would say take is easy. I think we all make the first year much more complicated than it really needs to be. Reading with your daughter will provide almost all that she needs right now. Most 5 year olds are naturally curious and will lead you to what they should be doing. Playing with bugs, making things with playdough, counting apples at the grocery store for you and then weighing them. Most of their learning at this age just happens with an involved parent. Also, she is going to learn a lot when you have your baby!
Children get so much socialization. Just look at your family! There are tons of groups to join, but IMHO, I would be careful and chose which groups you really want to be in. Too many activities can be stressful on your family and take away the joy of homeschooling. On the other hand, it's nice to get out of the house and talk to other families once in a while.
I'm in Chesterfield, so my support group is out here, but I'm always hearing about homeschool activities and groups over there in Troy. Take caution with co-ops, as they have a tendancy to try and recreate the public school atmosphere. I don't think you'll have trouble finding support. I bet if you ask your librarian, she'll point out the homeschoolers for you! lol... And start reading the books they have on homeschooling (you probably already have). Keep in mind that every family has their own way of homeschooling. It's good to get lots of different ideas and then take what you want out of it.
HTH, good luck to you!!
A.
