Being Crabby

Is my mood today going to reflect the kind of mom I'm going to be? I was awaken today over an hour before I would have liked to and now..... I'm crabby. I try to look at it like this: in just 1 months time, I'm going to be awaken before the sun rises many times. So why is it so hard for me to get out of bed these days? Maybe it's the protruding abdomen, the lack of energy, or maybe I just like my sleep. Any tips for the mom to be on ways to wake up positive so I don't end up making my husband breastfeed our son??
