Getting photos taken is exciting!
We know that this is new for you, and you may want to share it with someone that could make you feel a bit more comfortable, so yes it is possible to bring someone with you. That being said, take a minute and consider if having an audience will make you feel even the slightest bit self-conscience. Many people found having someone watch as they get their photos taken made them more nervous. If you think that you will feel anxious, try to avoid bringing someone because it will show in your final images.
Remember this session is for you, so try to keep that in mind when considering who to bring.
