Yeah, I took Caleb and mamasim into CAS and tried for offspring and I got them all similar to that oddball that looked nothing like Caleb.
So far so good, I managed to tweak Caleb a bit and fixed the eyes by simply changing their color, then changing them back.
Had some tweaks here and there to the jaw, chin and mouth and managed to get a more realistic daughter:

Now she's replaced! Will have to build their relationships back though.
@VentusMatt Never thought about doing that so thanks for the heads-up!
