How about if mum has a good pregnancy and can pick both the traits for the baby we can age the baby up a day early. I am thinking that having a happy pregnancy will be quite easy the first pregnancy but once those babies start arriving it will get harder.

A very solid idea, Rachel. I'll let that simmer in my head for a little while. If I implement it then it will be all or nothing as with the other requirements and stages — there's no partial credit. So, it would be either you get to pick two traits and age the baby up early or you don't. Just like the Toddler skills — you have to learn all 3. So, I'll think about it and what might be an appropriate reward/time savings.
I've been re-reading the rules and there's something I don't understand. This example is given:
But if there are 7 sims in the household, doesn't that include the original pair? So the original pair is being counted in the 7 but not in the 20. If there are 20 sims under the original pair, wouldn't that mean you've actually moved out 20 - 5 = 15 children? Or am I missing something here?
Schip, in that example I was first just talking about how many had moved out of the house. First you need to figure out the 3-pointer Sims. So, if you count 20 Sims underneath your original pair, and there are 7 members in the house when mom turns Elder, then you have moved out 13.

EDIT: Schip, you're right!

I flat-lined or something in my example in the rules. I'll reword it.
