Will I Ever Sleep Again?

My daughter is 5 months old. I feel tired all the time. Even now. I could really use a good nights sleep. My boys were "sleeping through the night" by now... I think. At least an 8 hour stretch. Oh, that sounds soooo good. 8 hours of sleep. I can hope. I can dream. It will come again, one day, eventually. People tell me I will miss this time, the late night feedings, the tender moments at 5am. They say, "You'll just blink and it will all be gove and she will be grown up." OK, maybe.. but right now I'm blinking, and the long nights are still here. I'm blinking.. and trying to keep my eyes open. Nap? Whats that with 2 other kids? Sleep in? HAH!
