I am a to be parent, and reading "happiest baby on the block" gave me some background on why this might be.
Basically it boils down to how we were before we are born in our mother's wombs. Same with car noise and rocking, and why it is easier to sleep in a car without realizing.
Congratulations. It might work for some kids, but my son never likes anything on him, we even cover him when he’s deep asleep and in a minute he’d push it away. And he’s been doing that since very little. Granted, the room temperature is comfortable and he has both diapers and a body on (with legs mostly uncovered). Personally I alwyas need something, even as light as a beed sheed around my torso for comfort.
What’s interesting about this find is that it may be related to the posture/positon of the body while sleeping and the heavy blanket probably relaxes the skeletal musculature and in turn the nervous system. I’m saying this as i noticed when i use the winter blanket, my body feels more aligned and pain free in the morning. One of the plusses of winter imo. Also noticed that when I sleep in a colder room I sleep/rest beter.
