Does your LO "sleep like a log" or sleep all over the place? I feel like I am always posting about K's rolling in her sleep. But seriously, I think she doesn't get good REM sleep. I will start her out at the foot of the crib and she will end up all the way at the top of the crib, usually wedged in the corner or with her head against the crib and curled around. She flips and flops throughout the night. She grunts, cries, wakes up for a bit, and usually falls back asleep. But I do have to go in and move her back down to the bottom of the crib again usually at least 1x a night when she can't move up anymore and cries. Sometimes she does a 180.
Is this a developmental thing - a precursor to crawling? Or just her normal sleep style? She has ALWAYS been a restless sleeper. I never find her sleeping in the same position or location that she started in. Even for naps.
Does your LO move in their sleep A LOT? I've watched her on the monitor at all hours. She seems to make some kind of movement at least every few minutes.
