potty-induced insomnia

perhaps it was the thrill of the olympics that drove susanna to dream big. or maybe liam picked up some random book on goal-setting from the library and has been reading it to her. whatever the case, apparently it wasn't enough for her to be diaper-free during the day. now she's intent on never wearing the things at night, either. my checkbook would be singing a happy tune if it weren't for the severe lack of sleep this is causing me. every night around 3 a.m., i awake to the sound of a shrill, "I NEEEEEEEED TO GOOOOOOOO PEEEEEEE PEEEEEEE!" and the rattling of her doorknob. seems she wakes up with the urge to go, makes it to the door, and then realizes that she can go no farther without some assistance. so i shake off the cobwebs of sleep, trudge down the hallway to retrieve her, carry her to the bathroom, plop her chubby self on the toilet, help her clean up, and put her back in bed. she then immediately returns to that peaceful state of rest as if nothing had even happened. unfortunately, i'm often awake for an hour afterwards, since i've struggled with sleep issues most of my life. you simply cannot abruptly wake up an insomniac in the middle of the night and then expect a happy ending. i am so affected by this recent turn of events that i've done my research (much of which, incidentally, has been conducted between the hours of 3 and 4 a.m.) turns out that young two-year olds physically do not have the bladder capacity to "hold it" for 10-12 hours. which means that there's really no hope for a full night's sleep at any point in my foreseeable future. so, remind me ... whose grand idea was it to potty-train her so young?
