It has to be. You can’t commit your life to something as major as parenting and not be tough. The sleep deprivation is only a portion of the job. Not only do you have to be awake, you have to be alert and safe. There is a small, helpless person in your care. You can’t just blindly go through the motions.
I was never good at being sleep deprived but I am definitely finding out how tough I am, especially this week. So I sit here about to get ready for working, having been up since 4 a.m., not knowing when I’ll sleep again. But I also sit here holding a most precious gift 🙂
