I grew up in household as a child & teenager with a Mother that just screamed on daily basis, gotta admit WE were the best behaved kids ever BUT she still screamed anyway.

... I think there are some parents out there that might actual be yelling & screaming purely because they themselves are not happy within themselves & take it out on their kids (like my Mother's situation).

Though I know being a parent to a 20mth old as much as she is gorgeous YES i have raised my voice at her a little more than i should have on a few occasions.

I promised myself i would not be a screaming Mother like my own Mother BUT you can have a moment where it just gets the better of you & you have got to get yourself into control &/or remove yourself from the room.

... Hey, no parent is perfect !!
