I say all this to tell every mom who is reading this that it is okay to have a quiet time in your day.
I learned a long time ago by several wise women that a wife should take time in the afternoon to rest. To encourage the kids to rest. That way when your hero (your spouse) comes home you are not exhausted. I do not rest often but I also do not feel guilty when I need to rest.
How do you keep going? How do you make it through the day when the baby is not sleeping or your insomnia is in high gear.
