What I'm after in this post is NOT to build an argument for men to leave their wives high and dry at any given moment. DON'T DO THAT. Rather, I'm suggesting a meaningful conversation about taking two to three hours at agreed, scheduled times that give dads the needed moments to destress and moms the predictability of how you will help and be in the moment when home. I would further venture to state that dads should be willing to provide moms with the same arrangement. In this way, married couples can combat the extreme challenges of raising children (especially special needs children) while holding on to a few moments of peace.
My wife and I have been using this approach for many months, and I can see the relief it has brought the both of us.
Don't be afraid of taking a break. It doesn't make you weak. In fact, refusing to take a break WILL make you weak. Breathe. Rest. Recharge.
