If you are a parent, then you have been sleep deprived more often than you probably remember (or would like to admit). Heck, many parents I know operate in a cycle of sleep deprivation wherein half of the time they are sleeping decently and the other half is a solid 3-4 hours of interrupted and crappy sleep. Consider this the rule book on how to workout while sleep deprived. When my son was born and put me through the navy seal-style sleep deprivation training, I couldn't find anything helpful out there to guide me in not giving up my workout habit without injuring myself or making the exhaustion worse. Enjoy! And note, whether its the job, familial issues, or the kids that's ruining your sleep, this will not last forever.
