Hello, we're 3 months old, we only sleep in a cocoon, only the hands are tied together, and then only wakes up from that the hands of the face. And during the day I cover only the hands. So she calms down, but without a cocoon, she falls asleep, and immediately wakes up from the hands. I can't figure out how to stop it ? Maybe someone share experience??
