When fawns are young they sleep more and stays where their mother puts them down to hide and sleep. As the fawns grow older, they sleep less and they will pick their own places where they want to take a nap.
When mother deer is ready to find her fawn she will go back to the place she last saw it. If she can’t find her fawn she will call to her young one by make grunting noises. When the fawn hears its mom it will take off running to her.
