How often do you get out of the house??
I too have been transitioning from a pretty active out-and-about style of parenting/life to a more home-bodied one. Six months ago we moved to a completely different state, where we know no one and are now a one income family. So, no more trips to the co-op and then out for coffee for me either!
I started looking at the Waldorf philosophy and homeschooling 'techniques'. They really emphasize a strong rhythm to one's day, and although I thought I would never be a person with a strong rhythm to my day, I had to start somewhere! It isn't set in stone, but we kind of have a flow to things that we didn't have before. I think I was more apt to get bored than my 3yo DS, and say "C'mon, let's go ___!" But I am finding myself actually wanting to stay home (or close to home) more and just BE.
The Waldorf philosophy also talks about the first cycle of people's life (approx the first 7 years) as a sort of dream time, where the child is not fully into themselves yet and is still completely open to the world. This is a time of imitation (as I am sure you have figured out!). I think that it is totally fine that your kids are home with you and daddy, what better role models could they have?
I was feeling stir crazy at first being home all of the time, and kind of feeling like I wasn't doing enough or it wasn't showing when I tallied up 'what-was-done' at the end of the day. When we started trying to have a rhythm/flow to our days I started taking it a lot easier. I stopped counting tasks or accomplishments. For instance, before at the beginning of a day I might have said to myself: I need to do laundry, the bathroom needs cleaning -especially the tub, I gotta remember to soak beans and make tortillas, and I should totally vacuum since I am going to be in cleaning mode... I didn't necessarily believe I would get everything done that day, but I still had it in my head as Needs To Happen! Now, I prioritize: Today we will do laundry. The end. We start laundry, we do some other stuff, maybe play, maybe clean the bathroom... we just see where the day leads us, but laundry is the only thing on my list. At the end of the day when the laundry is done, I feel good about our day! And usually because I am so much mellower about the day DS helps and we both have a great day and do MORE than what I "plan" (like, "hey, while the clothes are washing let's make lunch and have a backyard picnic!")
I hope this makes some sort of sense... it is kind of a rant.
