"So 7 kids is enough to keep me busy all day and at times I am pulling my hair out."

WOW!!!!! 7 kids every day? Congratulation! my sanity maxes out at 3 full time and my own 2 floating around. Once I hit 4 full time for anymore then 3 days a week my sanity starts to get comprimised.

No wonder you're tired. I was tired just reading that.
