sleeping beauties

i am not sure how i got to be so lucky. my son sleeps at least twelve hours a night. pretty much ever since he started sleeping through the night at a few months old. on his first birthday he slept for nineteen hours. it is his record to date. people told me the next one will be different. there is no way you can have two children that will sleep that well. enter our daughter. she is no different. she sleeps even longer. about fourteen hours a night. on average. to date yesterday was her record. she slept for seventeen hours. she went down for a 'nap' at 3:30 tuesday afternoon. and didn't wake up until 8:30 the next morning. and i know what you are asking yourself. diapers. rarely do i have spillage. rarely. thankfully. and i use store brand. always have. i understand they must wake up during the night at some point. but i never hear one peep loud enough to wake me up. speaking of which. if i slept for as long as it took to make up for all of the sleep i have missed in the last twenty-six months i wonder how long i would sleep.
