The Necessity of Naps

I did not write a post early this afternoon because today I have been feeling lousy and needed to nap when Noah was napping.  Noah decided to wake up at 7:30am even though we put him down at 9pm the night before.  Most of the time he sleeps 12 hours, but he woke up with a...ahem...surprise in his diaper.  That always wakes him up.  After I changed him and fed him, he fell back asleep relatively soon and thus I followed suit.  I was very thankful that God answered my prayer for more sleep.  When I really need more, I always ask for it from Him and many times He grants me this request.  When He does not, He always gives me the strength to stay awake and suffer for His glory and for the benefit of my son's needs.
 Now that Noah is a little bit older, I sleep quite well actually.  But as most mothers understand, that was not always the case when Noah was little bitty baby (was Noah ever really a little bitty baby?).  Even though there were very, very few benefits from having Noah be so ill when he was born, one of the only nice things was at night I could go to sleep and have the nurses take care of him.  That was about the only nice thing of having him in the hospital for so long.  When we took Noah home, I realized within a day that I had been very spoiled with the nursing care I had available to me.
After a day or two of constantly waking up and feeding him, I specifically remember thinking: How does Amanda Ewer do it?  I mean, I only have one child and I'm about ready to throw in the towel- she did this FIVE times (she is about to do this for a 6th time as I understand)???  My body hurts so much and I don't have the strength to breast feed anymore.  Then my mind went to this time when Amanda was feeding one of her little ones and I thought how she must have cosmic-strength, like some sort of super hero.  I came to realize later that when your baby gets older, he/she does most of the work and you just sit there.  But, at that point I was NOT thinking clearly and I had yet to experience a feeding that didn't require me to do most if not all the work.  
 (Just as a side note, Amanda is an older sister in Christ to me that I know from Bloomington.  I know many women who have been very fruitful in motherhood, but for whatever reason, her example stuck in my mind during my sleep-deprived trials as a first-time Mama.)
I have never been a particularly good napper, but man, am I grateful to God for naps now.  When Noah sleeps, I can be a very productive home-maker and clean the house and get supper started.  But for those days when I need the extra rest, I am grateful for a schedule that can leave a little room for some catch-up sleep.  Now I am just dreading the day when Noah realizes that he doesn't need a nap anymore.  Any advice for keeping your kids on a nap-routine until they graduate high school?
