have 3 ds, 3, 5 and 7 years old. Have bascially brought them up on my own and didn't think i had done a bad job, they are all very close to each other, polite, help around the house and were generally well behaved untill about 2 weeks ago then BOOM they all changed, fighting constantly, not using manners etc. I had to pull my 7yo Ds off my 5yo Ds as they were fighting pretty bad 2 nights ago resulted in me being caught in the cross fire and getting a broken thumb! What could change in theat time because i have no idea, any help or suggestions greatly appriciated as i am beggining to feel out of my depth :-/
