I'm so tired!

Oh my goodness, I am so utterly tired today. I think it is being pregnant and also having a toddler who was up at 3:00am for the last 2 nights. I'm not sure why he is waking up, but after about a half hour or so he will go back to sleep, but mommy can't seem to get back to sleep at all. The last time he went through a wakeful period like this he was getting some teeth, so I am wondering if a couple more are trying to pop through. I really hope he sleeps tonight. I don't know if I'll be able to function tomorrow otherwise.
