I have lots of problems....but one think I don't have is kids who fight a lot. My kids are 9 (boy) and 5. (girl)..
They have different interests and hence can spend time doing their own thing...also the little one accepts that her brother is older and lets him take the lead a bit. She is easygoing and shrugs things off quickly.
Maybe try and do things alone with the kids a bit more and let them develop different interests...
also make sure dad gets involved more...
and a reward system might help.
I fought a lot with my siblings (4 of us ..very close in age)...but now we are all very close....so keep up hope..
