My partner of one year has two boys SS12 and SS9 - and I have one BS 11. Unlike many here, things with the kids are going really well - so much so that we're about to move in together.  SS9 has some loyalty issues, but hey ho. But my SO doesn't allow them to treat me badly and we back each other up and when I do stuff for his kids he is thankful and appreciative and he does so much for my BS that it's really a good trade out.
