A childhood home becomes strange when entered with adult eyes.

The doorways are lower than you remembered, the yard is smaller, the whole place has shrunk to the scale of an ordinary house. You are seeing it with adult proportions and adult knowledge, including things you did not understand at the time. Both versions are true and they do not fit together comfortably.

Let the visit be strange without needing to resolve it. You are not betraying the child who lived there by seeing it plainly now. If it stirs something up, it may be worth talking through with someone rather than filing away.
