I've never been what you'd call a "sound sleeper." I'm actually kind of a light sleeper... but prior to having kids, I usually slept quite well.
These days, however, sleeping through the night is a rare thing for me. I am often awoken by any number of things. Here's the top four:
1. snoring (not mine)
2. crying in the middle of the night ("Where's my bear? I can't find my bear!")
3. nature calling (what's up with that? does that just happen after having babies? or after turning 40?)
4. crazy dreams...
...like last night... I had not one, but two dreams that caused me to sit up in bed and scold my 4-year-old son in my sleep.... until I realized it was just a dream. In the first dream he was goofing around, spraying potty all over the back of the toilet seat and on the floor. Ack! In the second dream he was standing, balancing on top of our 4' chain link fence! Both, in real life, are enough to make a mother's blood pressure rise a little.
Oh, the life of a mother... even in her sleep she is admonishing, beseeching, sighing...
