nestle down (in something)
To lean or lie down (into or on top of something) in a snuggly, cuddly, secure manner. After the kids were in bed and the house was tidied up, we finally nestled down in front of the television to chill out for a while. I love nestling down in bed at night after a long day of work.
nestle down (in something)
to settle down in something; to snuggle into something, such as a bed. They nestled down in their warm bed. Please nestle down and go to sleep.
