Why not for me?

My beautiful 5 month old daughter is the apple of my eye. The sunshine in my day, the moonlight of my night. But she will not nap for me. EVER. Day after day we dance the pas de deux consisting of nursing, burping, diaper changing, putting down, picking up, kick ball change, and repeat. It is a paso doble in which I can not tell which of us is the stubborn bull. In the end, I surrender as often as I triumph, still learning her cues.
But today, she slept. It was rather easy. I nursed her, the husband changed her wet diaper, I nursed her some more until she fell asleep. Then the husband fell asleep. I left them cuddled on the bed (yes I know, dangerous for a myriad of reasons, including bad habits) to get done at least one nagging chore - take down the Christmas Tree when it was still a tasteful amount of time to have it up, as history has shown that sucker can still be up come Valentine's Day. So I took down the tree, forgave myself for not vacuuming yet so as not to wake the duo, and somehow tetris'ed the decorations back into the storage containers. Then sat here. Watching the clock.
TWO HOURS! TWO WHOLE HOURS!!! They slept - SHE slept - my little twinkle star slept for two hours. I guess the secret is to sleep with her, as she has slept for two hours in the past if I napped with her. So, I guess I must surrender to napping. One more excuse for having dust on my shelves, dishes in my sink and dog hair - everywhere. She needs to sleep, and apparently, she needs us to do it. So, I am going to err on the side of excellent mothering, even if it perpetuates my subpar housewifery. I was never very good at the cleaning bit anyway.
