We help are wives out in caring for are children when they would like to participate in the study (brainwashing) sessions at the Kingdom Hall, you cant rise your hand and speak when you have a baby in your arms.
In this way are wives get to show their utmost devotion and understanding of Jehovah and his will and purpose for mankind.
We still don't let them teach or give talks though because Jehovah in his written word the bible says they aren't to speak bible teaching when men are present and capable in doing that.
Woman are to be subjective to men in all things, including wives to their husbands.
