Welcome to YT.
Holly is such a pretty name for a little Christmas puppy. Don't worry about her being taken too soon from her littermates~really that is in the past and you need to work on now. You have been given good advice to distract her with a chew toy. She is just a baby and really does not know any better. It will all come with time. It isn't too early to work on basic things like sit. You will be amazed at how quickly she will catch on~and she will be the star of your puppy training class at the end of March.
When she is biting inappropriately you need to distract her with a chew toy. If she is acting inappropriately you need to turn your back to her and ignore her. Another thing that you can try are the Himalayan Chews. They are very hard and will keep her busy for hours. Everyone on YT is just raving about them.
My Doodlebug was doing tricks at a very early age. My suggestion would be to use Cheerios for a treat. All you need to do is move the Cheerio from in front of her to above her head in a backward motion. She will sit. This will also help to distract her from her biting. There is a fine line between playing and over stimulating your puppy. Try to keep the rough play to a minimum. Good luck with your new little girl. She is just adorable
