I know this is not a medical problem, but maybe some of you more experienced moms can help me. My 4 kids are constatnly bickering. My kids are all adopted and we are now fostering a 14 year old girl. My 21 year old son just moved back into our home from Las Vegas and both he and the 14 year old girl seem to argue a lot. These kids are giving me a headache every weekend. I know this is an adjustment period, but I don't know how much more I can take. How do you guys handle the arguing?
