In recent times I have been cheating to give my sim children Long Distance Friend first because it breaks my heart when I get a popup that an aunt or uncle is no longer their friend just because they didn't have time to talk to them for a few days.
In the past, Observant was always the first one I gave them because I like the charisma skill and knowing 50 traits is good for one of the challenges that come with that skill. Apart from the points needed for Long Distance Friend, my children don't get any more until they earn the points and I always give the same set of LTRs in the same order and, once they are older and their personalities are known, I give them LTRs specific to each sim. By the time my sims are teens they all have (in this order) Long Distance Friend, Observant, Fast Learner, Steel Bladder. After that, they get LTRs that suit them.
