I don't remembering valuing a great night's sleep as much as I do now that I have a child. The last good night's sleep I had was drug induced during pre-term labor when my OB discharged me from the hospital with an Ambien and told me to go straight to bed upon taking it.
Flash forward to two years after giving birth and while sleep is better now than during the infant nighttime nursing sessions while still having to get up for a traditional job it still isn't amazing. I think I'm wired to wake up to the little peeps from my guy but lately I find I'm just waking up and cannot fall back asleep. Caffeine becomes my crutch and on days when my guy decides he won't nap I am just beside myself.
Being a working mom or not when your child decides not to take a nap, go to bed, or wake up at 2 or 3AM you feel like a zombie. I have been reading some great books lately and the best piece of wisdom I have read is that all children go through "seasons" and to just relax and remember how quickly they grow and move on to something else.
