I need to get this out

I am evil mom today.  I am enormous and cranky and tired and have no patience.  DS is going down for a nap and jibber jabbering away and all wound up in hid bed which means he won't fall asleep and I'll be here in 2 hours with an overtired toddler, too late for a nap, pulling my hair out....

If I go in to tell him to be quiet and rest it will just come out short and snappy. I just want to scream.  I worried about how much of a b***** I'm going to be when I'm overtired with a newborn and my toddler is trying my patience.....ugh....Not sure which brings out the worst in me - being overdue pregnant or overtired with a newborn
