to change or not to change...

To change or not to change, that is the question... Caedmon fed really well at 5:30am, then fell promptly back to sleep, and, until he takes another turn in his development and routines, he won't wake again until around 9am.  Ahhh... peaceful bliss.  Except, one whiff of his bottom has just told me that Caedmon has soiled his diaper... so do I change him and wake him, risking the likely chance that he will not fall back asleep?  and thus, beginning the unhappy cycle of no sleep-->overtired, fussy baby-->difficulty falling asleep-->no sleep... Or do I let him sleep, subsequently allowing my son to stew in his own mess?

I have chosen the stew.
