My 6mo old has 3-5 overnight wake-ups every night. I had really bad sleep disruption late in pregnancy, too. The last time I slept more than 4 hours in a row was sometime in December.
Baby typically has one 3 to 3.5 hour stretch of sleep, then the others are 1.5 to 2.5 hours long for the rest of the night. He goes back to sleep quite promptly after eating, but he's up again so soon.
Tell me it gets better? If your LO was similar, was there anything that made it better?
