Hello. I was playing my family for Metro's Immortal Dynasty challenge and I got pretty frustrated when I wasn't able to choose the traits I wanted for my heirs. Not that I wasn't doing my job as a Sim parent, because I was able to choose certain traits. Just that the ones I wanted weren't on the list. So, as I am a player who likes to plot out my future moves in the long running dynasty games, I decided to find out what traits were available for children at each development stage. Below are my results:
Available to be chosen at birth (up to 2 traits): Absent-Minded, Artistic, Athletic, Brave, Clumsy, Couch Potato, Easily Impressed, Eccentric, Evil, Excitable, Friendly, Genius, Good, Grumpy, Hates the Outdoors, Heavy Sleeper, Light Sleeper, Loner, Loves the Outdoors, Neurotic, Perceptive, Slob, Virtuoso
Available to be chosen when toddler becomes child (up to 1 trait): Adventurous, Ambitious, Angler, Bookworm, Can't Stand Art, Computer Whiz, Coward, Daredevil, Eco Friendly, Family Oriented, Frugal, Good Sense of Humor, Hot Headed, Hydrophobic, Inappropriate, Kleptomaniac, Loser, Lucky, Mean Spirited, Mooch, Neat, Never Nude, No Sense of Humor, Over Emotional, Party Animal, Perfectionist, Photographer's Eye, Snob, Technophobe, Unlucky, Vegetarian, Vehicle Enthusiast, Workaholic
Available to be chosen when child becomes teen or when teen becomes young adult (up to 1 trait per transition): Born Salesman, Charismatic, Childish, Commitment Issues, Dislikes Children, Dramatic, Flirty, Great Kisser, Green Thumb, Hopeless Romantic, Natural Cook, Savvy Sculptor, Schmoozer, Unflirty
All choices from previous transitions are available unless you chose a conflicting trait (IE if you chose Good, Evil is removed from your available future choices).
I also made a rather lame attempt in Google documents to make a table form of the same information. But if you'd like a copy for your personal reference, feel free. It can be found at:
