I homeschooled my 5 children for many years, 2 graduated from homeschooling in fact. This is my advice.
As many people that reply here that's how many opinions you'll get. It's not a decision to be made lightly and requires a great deal of time, energy and patience from you. AND it's near impossible to do without the support of your husband. BUT it is the most rewarding thing I've ever done. And don't let anyone tell you that you're not qualified because you don't have a college degree. There are so many helps out there for parents it's mind boggling, can be too boggling in fact.
This website offers some great help and advice http://homeschooling.gomilpitas.com/methods/CharlotteMaso...
If you can find some local families that homeschool that would be a wonderful resource. You can ask them all kinds of questions, perhaps sit in on their day. This is the time of year for conventions as vendors are wanting to sell you their curriculum. Those are great places to go to hear various speakers, get ideas and some great deals. However, you can fall into the trap of OOOO I call it where everything looks wonderful, fun an a must-have and you can go bankrupt & end up overwhelmed. Best to do some homework (no pun intended) before you go in there. Most women I knew went to these things with a literal shopping list having done their research ahead of time.
Best thing you can do is find out what curriculum you want to use & stick to it. It's less frustrating that way, consistent for the children & less expensive in the long run. Right now with the kids the ages they are I would look at a free online resource called www.letteroftheweek.com I used this with my youngest for preschool/K and we loved it.
And we also always belonged to a homeschool support group. One group we were very active with was a education coop where we came together each Friday for 12 weeks in the Fall & 12 weeks in the Spring & did coop teaching. My kids took classes (4-1 hour) in subjects such as Algebra, Science, Drama, Music, Latin, Spanish, History and Writing. It was wonderful!
It's really hard to condense years of experience into a short reply. I know that I treasure most every moment we home schooled our children. Like with other aspects of parenting, there are days I would've rather flipped burgers at McDonald's than teach my kids. But I knew those days would pass & they were few & far between. THe time I got to spend with them, getting to know them the way I do, share my faith with them, and to do things that ps kids didn't get to do was wonderful!!
