What Was That For?

Last night, Tali woke up around 1:15 and started screaming, not crying - screaming bloody murder. I let her scream for 15 minutes and since she wasn't calming down I went in to see what was wrong. (Lucky for me, I am the only one who can calm her when she wakes up like that so it's not even worth H getting out of bed - he's tried before.) No fever, no dirty diaper, no spit-up, she just needed her mommy. As soon as I picked her up, she stopped. It took her about eight minutes to fully catch her breath and calm down and then I put her back down. After that she went back to sleep. I, of course, laid awake for an hour waiting to see if she woke up again. She didn't.  Since I don't know what the problem was, I am going to guess it was teething-related. I am so not a fan of this teething thing and she doesn't even have teeth yet! Does this really go on for two years? Will I ever get some sleep?
