You have Emerson, who is 14 years old. You have Sienna, who is 12 years old, and You have Seth and Emily, who are twins and are 10 years old. You also have an Australian Shepherd named Sterling. Emerson has grown into an amazing teenager, although he is sort of in his "rebellious phase" right now. Sienna is exactly how you would expect a tween to act. Seth and Emily are still young and still have a lot to learn.
