Some of us like "baby land".
It's easy to continue to do CE's for your license. I go to as many local classes and conferences that I can and you can do CE's online.
If your husband has a good job with bene's, you can certainly go on his insurance. You can also look at your budget to see what you can cut to make it easier to stay home.
You could do the per diem thing too.
Please don't feel guilty about wanting to stay home to raise your kids. It's a valid choice. And one I prefer.
As to the boredom issue - that reminds me of my when my kids mentioned the word "bored". They didn't want to do that when mom was around . . . .
I think we make ourselves bored. We can be bored at work as well. I look for things to keep my mind engaged and think exercise is a great way to not be bored. There is a trail locally - it is about 1 1/2 miles and loops around to a gorgeous waterfall. I put one kiddo on my back and held the hand of the other one and we'd head out on a trek a couple of times a week. I'd ask other friends with kids to go with us and the conversations would usually end up making us laugh together. I can find lots of things for my kids to do and am not a fan of putting them in front of a tv or giving them video games. "Let's go have an adventure!" and out the door we would go. I loved that part of my life and miss it. Three of my kids are adults and my last is 11. He and I still walk the waterfall loop or go explore the lava caves or head over to the lake to fish.
Life is never boring but some people choose to be bored. The concept of boredom entails an inability to use up present moments in a personally fulfilling way. Boredom is a choice; something you visit upon yourself, and it is another of those self-defeating items that you can eliminate from your life.
