Mouse Squeaking?

How long have you had the mouse for? Since mice are so small and us being so much larger than them it is common for them to be scared. They need to be use to your scent and understand you. In order for her to adapt to you the way you wish for her to you are going to have to be patient. She needs to know that you are not going to hurt her and that you are just trying to show affection and be playful. Give her time and just keep making sure that you are doing your part as a owner eventually you will grow on her and things will be how you want. It helps to have more than one also so that the mouse is not alone and is use to a partner or a friend. Hope this was helpful.
