Will they ever stop fighting?????

I love my monkeys with all my heart, really I do, but some days...............oh I wish I could leave them at the zoo!!!!!!! D and N are having a really hard time right now, I am not sure why but all they do is fight! Its usually over something very petty and stupid but it does not matter, they have to fight and scream and make my life not so fun as a stay at home mommy! Mike has gotten to see this week that it is not just me, they are really fighting..............I know they will out grow it and eventually stop fighting at least so much, but really............does it have to be so loud???!!!
