Aww man. A doting aunt. A superstar one at that. Let's hope he doesn't get spoiled rotten by the father's side of the family.
Still...she's in junior high, huh? She was in kindergarten back then, though we don't know which year. Assuming she was in her first year, it would've taken her 6 years to hit first year of junior high. I think it's safe to assume she was as young as she possibly could be considering she's still in Junior High and she didn't look like she was in elementary school when her nephew was born.
So this is set 8 years after the original at the very most.
