My head hurts

It's great to put in all your effort and "finish what you start" so to speak. But think of what all your energy and good intention and passion could be doing for 3 children (and up to 3 families) that just "fit" with you. Those children could flourish and grow and you and they would benefit greatly. These children may just need a change. Part of that change may be to split them up. It is hard to spend 24/7 with your siblings...of course that is what many families do but maybe the kids just need a break from each other they can reach their potential and so when they come back together at the end of the day they are refreshed and enjoy each others time.

You need to make a gut call on whether to push through and hope for improvement or whether it is best for all to term. There is no failure in deciding that they just need a change and that you can do more and better with another set of kids.
