try to get the snake interested in eating the mouse by dangling it a little more.
one week of not eating should not be a problem for your baby bp. you should get a scale and keep up with measuring your snakes weight so you can tell if he is gaining or losing. bps can go off feed for many months and it can be stressful for the keeper. a scale will allow you to view any fluctuations in weight allowing you to make more informed desicions when it comes to feeding and the health of your bp.
keep handling to a minimum and try f/t thawed again next feeding day.
