I aged up Mini a bit too. People have complained that Sin looks like she aged up years instead of months... If you think she does or doesn't, it's fine. She's a demon... how fast should she grow? Have you met a demon? They're monsters and they're aging at a rate that lets me tell the stories I want to tell with them. Them being eternal five year olds isn't what I wanted... plus Mini was talking in full sentences within like a week of being born. They're advanced for their ages...
