AS IF I need to be losing sleep right now...

For the last few weeks, the short nights have become intermittent nights.  I sleep for about an hour at time before I wake up and can't go back to sleep for quite some time.  I am so tired in the afternoons that I can hardly function!  To make matters worse, my four year old is struggling with all of the change (she starting preschool on Monday and she's seldom been away from me and the baby is coming and she's tripped out) and some yucky tummy issues. 

Just whining mostly, but is anyone else really a little torqued that we're losing sleep BEFORE the baby arrives?!
