As a breeder, I can tell you that their personalities change. The calmest one can end up the being the roudiest by the time it is time to go and visa versa. Though I'm sure you are wanting to pick one out now....go with your instincts. Take time to watch them and play with them. Chances are they are all going to be able to adjust to your one year old. Most people choose the one that chooses them first.
