I put her down for her first nap today on her tummy with no swaddle. My active LO slept for 1 hr and 20 minutes and then I hear a yelp. I went into the room and found that she had turned 180degrees from the position I had left her! And she yelped because she seemed to need help to turn to somewhere and I don't know where!
As a result of that, she woke herself up.
Do your LOs start moving a lot in their bed during this period of time?
