Hi Lydia - it's highly possible that when a soul goes out of body at such a young age a soul-exchange could happen - yes. That would be becasue the soul is not as fully embodied in the earlier years and as you say, the personality is not yet fully developed - hence there's less identification with the bodymind.

Personally that, even if that had happened, I wouldn't get too hung up about it. The real question is, how you integrated through the years and how does your soul inform your reality now?

The real challenge for a soul-exchange is where it happens in a fully mature being - because the integration can be really tough and confusing - for the being themselves and the people around them.

Blessings
