Congratulations Samantha!
Welcome to HOD! I'm with you - I LOVE being able to be at home with my kids, and we love our days spent homeschooling with HOD.

You're in for some great fun and learning and growing over the year! I know that I was especially thankful for the fact that the HOD guides are open-and-go during the early months of pregnancy. If you read through the introduction, you're good to go. You can just open the guide and enjoy your time with your kiddos every day. I do have to say that I personally love our homeschool days much more when I'm feeling energetic and nausea-free.

But, I found that it was still enjoyable even during that time. I also found that continuing on with our homeschooling was better for me and the kids (even if I wasn't feeling great), because the other choice was me laying around and them being left to do whatever. And, "whatever" usually means watching TV or jumping off beds or arguing or something else that is going to make me feel much more crazy than continuing on with school and having a productive morning with some routine.
I also wouldn't be too scared of outside activities either. I guess it depends on how overwhelmed you're feeling. If YOU think it's too much, then let something go. If not, they could actually be helpful. I know in my early days of homeschooling (Grant was 7, Allison was 3, and Garret was 1) I really enjoyed our times out of the house, too. I found this to be especially true when I wasn't feeling the greatest during early pregnancy - maybe because it took my mind off it?? I was actually pregnant for 4 springs in a row (and miscarried the 1st 2 towards the end of the 1st trimester, but had all the morning sickness that comes with a normal pregnancy first). How do you feel about the activities you have planned? Are you planning them because you feel like the kids need them and you'll be letting them down if you don't (but personally dreading them)? If that's the case - drop them. The kids will be a-ok and better off with a mom who's not stressed.

But, if it's things you're looking forward to, and you'll be getting some other mom interaction while you're out, you might come away feeling more refreshed than stressed - so feel free to hang on to those activities.

I personally am at a point in our lives right now where I love to stay at home and we don't have regular committments outside the house (except on Sundays for church and AWANA). But, we used to have a homeschool group that we got together with weekly and a ballet class (for Allison) and it was worth the effort to go. The kids and I all loved it! For us, our committment to homeschooling comes 1st on the responsibility list. So, if something is getting in the way of being able to do that completely and happily, it has to go.

Those "extras" are extra. But, if it's something that refreshes me and is enjoyable for all of us, we add it in for seasons in our lives when it works. (And, yes, I have learned this by being over-committed at times and realizing it makes me a stressed, snappy Mom.)
You are in for a great journey with your kids!
