I need help with flashback scene characters

[GloomySquid]

Maybe this old forms post could help?

Making the character in a flashback match the reader's CC

So I have a character that the readers can customize, but I want to create a flashback of that character when they were a child- with the reader’s customization. But, the younger version of that character will have slightly different attributes (to make it look more like a kid) so how would I do that? [help]
