Congratulations on your decision to homeschool. I have done so for my two girls for the last 8 years. My oldest is a junior this year and I pulled her out after 3rd grade. My youngest has never gone to public school and she is doing fabulous. First of all, you are already doing the first step by asking for lots of advice. Everyone goes about it differently and what and how you do this will depend largely on your own child(ren). You may have to sift through a lot of information, but you will find what works best for you.
I'll start off by saying that everyone chooses to homeschool for different reasons, so don't let anyone deter you. Our society is built around the public school thinking...schedules, vacations, etc. But, there are many groups out there to help you out. Some are just for support and some actually help each other with teaching. You didn't mention where you live, so I'm not sure what your state requires.
You can go online and check out your states department of education and find out what the State requires. Some just want you to register which consists of filling out a form basically stating that you are going to homeschool. Others want you to test just to be sure you are actually doing it!
Then, I would suggest you find a homeschool convention. Most states host one usually around this time of year. There are vendors for all kinds of cirriculum and activities plus workshops about getting started, etc. If you can't find a convention, try finding a group in your area. I'm sure you'll find something online, but a lot of times word of mouth is the best.
This is one way to keep your son involved with other kids. But, ironically, socialization is very rarely an issue. We attend church, so most of my girls get their interaction there. But, they also took dance lessons and for a few years, we played soccer at the YMCA. Again, do a little research and I'm sure you'll find something.
Cirriculum is probably going to be the toughest challenge because there is SO much out there!! One reason I like to go to the conventions is to get a good overview. You can talk to the vendors and look through the materials to see what you like. Don't get discouraged if you have to try a couple of different ones, either. The first couple of years I tried different ones until I found one I liked.
As far as balancing everything, again, it will take some time to find what kind of schedule works for you. You may find that the 3 yr old will enjoy learning some things along with him! You can give her some simple letters and numbers pages if she wants. Anyway, one thing that REALLY helped me was to just turn off the phone for whatever time you are going to be working with him. Let the answering machine get it. You may be able to sit down with him while the baby is sleeping. Or, you might be able to give him one task to do and check on him a couple of times while you do something else nearby. Remember that you have control of the time. So, if you need to take a break, it's ok. I kept a notebook at first of the time we spent and how much they got done. You may want to do one or two subjects a day, or a little of each subject.
I would probably spend the most time at the beginning letting him learn to read...this takes more work than most people realize because we don't really remember learning to read! And, then I'd work on learning their numbers and math facts. Even if this takes you all year to do just that, he'll be ready to take off quickly after that.
I know I've been longwinded! If you want to email me directly feel free. [email protected]. If this is something you want to do, you will be able to make it work just fine! Just take one step at a time, Mom, and you'll be great!!
Good luck!!
