It's Nice to be Understood

I have been so unbelievably exhausted lately. I have been getting about 9 hours of sleep at night, but by the time Sophie's nap time rolls around (sometime around 1pm or 2pm) I am beat again. And if I don't nap when she does (because let's face it, when else am I going to get any time alone?) then by 5pm I am so tired I literally start to cry. I remember this happening last time too, but I stopped working around now and didn't have a 2 year old to take care of. Last night by 6:30pm I felt like I was falling asleep at the wheel. Luckily Shimmy had been home all day, so I told him I couldn't handle it anymore and went to lay down. But, even if someone else is around to hang out with Sophie, unless she is also sleeping, I cannot fall asleep. My guilt keeps me up. I don't know why I feel less guilty about stumbling around and crying from fatigue while she tries to play with me. It makes a lot more sense to allow myself to take a cat nap. I don't understand the mommy guilt, I just give into it. (This could turn into a whole post in of itself.) BUT, last night as I was trying to ignore the guilt and go to sleep, this is what I heard:
Sophie: "MOMMY MOMMY MOMMY MOMMY MOMMY MOMMY!!!!!!!!!!"
Shimmy: "Leave Mommy alone. She's taking a nap. She's very tired. It's hard work growing a baby. You don't know, you've never done it before."
Feeling elated that Shimmy totally "got" me and didn't seem to think I was just slacking off, my guilt melted away and I took a nap with a smile on my face.
