ETA: I see a poster below has mentioned allergies. Do you or anyone in the family have allergies? If you end up being allergic to the cats, it will not be a good thing. It will be traumatic to give them away, so you are left with doing immunotherapy. I chose the later so we could keep the cat our kids love. I went for these shots for years. It helped, but it was a huge time commitment. Rule out cat allergies before even considering getting the kittens.

I'm the dissenting vote, here.
Sorry, but I just don't see this working out very well. You home school. You have three little kids. You've mentioned before that space is an issue in your home. You've talked in the past about wanting a little time for yourself. You've just added a new puppy, and now you're considering adding two more kittens?
It's great that the kids are helping now, but what happens when they don't? Who will all of these new responsibilities fall on? It's not just walking the dog (in the frigid Chicago winters and on rainy midwestern days), but now cleaning two litter boxes, ensuring three animals are fed and watered, playing with them, brushing them. And let's face it---even the cleanest animals create more housework. More vacuuming, more sweeping, more moping, more using the sticky tape roller thing to get all the hair off of your furniture and clothes.
Your kids can't yet drive to the grocery or pet store to get food and litter, and I can tell you that hauling big bags of cat litter, cat food, and dog food is no picnic. (And I don't even have to deal with snow and ice anymore). We get the recycled newspaper litter, and to decrease the trips to the pet store, I buy several huge bags all at once. Do you have places to store these? If not, you'll be running to the store a lot more.
Who will be responsible for taking these young animals to the vet for all of their check-ups and vaccinations? Have you considered all of the costs involved with having three pets? It goes far beyond food and litter. Are you prepared to cover costs of any medical emergencies or long-term illnesses that your pets may develop?
What happens when you go to Ireland or take that trip to Greece? Do you have someone who will come and take care of three animals, or will you board them? Boarding three animals for an extended vacation will cost in the thousands, if you are going with a reputable establishment.
You said it yourself that you think you "have enough living things in our house." Trust your gut on this one, J..
Would you be insane to take this on, you ask? My verdict is yes.
