Sleep deprived

Okay, having a new experience lately that I haven't been able to sleep at night. Wierd for me, because I have always been a good sleeper, yes I am pregnant but what is up with this. I'm suppossed to be tired all the time, not be an insomiac. The longer I am pregnant, the more i realize that being pregnant is not just about creating a life, it is about preparing for parenthood and learning how one to be sleep deprived and to take care of others when I don't feel good myself.
