Ok so my daughter likes to fall asleep to the sound of “Heavy Rain” , like she be out like a light; but I noticed once she is in a deep sleep she jumps a lot in her sleep, and raises her arms as if she thinks she is drowning..🤔😂. I’m thinking we need to find her another sound to fall asleep to.. my poor baby. Lol
