I can't sleep with out my baby.?

We cosleep. It's 3am and tonight she is tucked away, warm and snug as a bug in a rug while I am cold and typing on the computer...... lol...... Hm..... Can anyone relate? I'm so tempted to take my blanket and go lay on the floor in her room. I'd feel better, but I'm afraid she'd sense me or smell me and wake up. She does that a lot so when she naps etc I usually stay out of her room.......
