How was the childhood of Harry Potter's son different than Harry's?

Answer 1

I am assuming you mean Albus, since he is the main character in Harry Potter and the Cursed Child.

Harry's son Albus had a childhood that was very different in many ways. First, his parents were alive, and he didn't ever have to get farmed out to relatives. He knew about his magical identity from a young age. He learned to resent his overbearing father rather than to miss an absent father. He also had siblings to deal with, and had to grow up in an environment where his father and his father's friends are madly popular and he often gets overlooked.
