MMMMMMEEEEEE TTTTTTOOOOOOOOO! I really think its a mix of all of the above. The weather is changing, we are stressed over school starting, there are money issues due to the change in kids for most of us. Plus because of the weather, there are ALOT of sniffles and headaches. Hmmm, you add in your time of the month and...those kids a "treading on thin ice" ha ha. All my kids know when I get a certain "look" on my face, they just go play quietly until they see a smile. I guess we cant be perfect ALL the time!!!!!!
