NAH As I don't know what I'd do in your position. It would be a lot to take on that many kids at your age. However, don't expect any happy reunions with any of these siblings as they will consider you not family as you chose not to take them in - same goes with the 6 y/o as they aren't going to be happy with her either as they are going to see her as the favored sibling by you. These are family members who are never going to talk to you after you making the choice to put them in foster care (which is a terrible system where many kids are traumatized) and will no longer consider you family. Keep in mind this will be the consequence to the decision you are making.
