being that she is so new, I would just tell people sorry but she is a little overwhelmed, so they can look but not hold. That should save the pass the parcel with the new baby.

As for the rest of the time, if you have a sling I would suggest using that, so that even if it gets noisy she is close to you and feeling safe. She should sleep for some of the lunch part so maybe ask your inlaws if you can put her pram in a room at the opposite end of the house from the celebrations so she can sleep.

Hope you and your DD are home to share her first christmas, so exciting
