no rest for the weary

She was up again at 12:30 and I was so tired, that I fell asleep feeding her. I woke up at 3:30 and laid her back in her crib. Little good it did me. She was up again at 5:30 and fought everything to avoid going back to sleep. Now she's whining and complaining in the jumperoo. She keeps yawning and I know she's exhausted, but she just won't sleep. I don't understand what's going on. I know she can sleep a straight 10. What am I doing wrong? I'm tempted to just do cry it out, except I'll just end up with a hysterically baby.
