Extreme raising kids challenge

I came up with this challenge idea and first thought would be just a bit of fun but so far it has been the only challenge in this game I haven't yet been able to complete... 

I created a family with one normal adult sim
and six toddlers: witch, genie, werewolf, vampire, faerie and ghost.

I bought them a lot and built a house with no cheats or money codes

The only adult sim I created is not a big fan of children... Her traits are dislikes children,
commitment issues, ambitious, flirty and workaholic. 

At the beginning I had my game on normal ageing mode and the idea was
to count one point per each trait you get to choose yourself when the
toddlers are aging. If your toddler get taken away from you by the social
workers you not only loose the possibility to earn more trait points with this
child but also get one minus point. I was planning to end this challenge when
all the kids have reached young adult stage.

On the fifth day with only two more days for my toddlers to age I noticed
that only four of them can go to toilet on their own, two of them can walk
and none of them can talk...

Before you manage to teach all of them how to use a toilet there's no way
you can even dream of teaching them to walk or talk. You only have time
to take care of their basic needs (if sometimes even that).

The only adult sim hasn't had a change to start her courier yet and because
I'm not using any cheats can't afford to hire a babysitter. I managed to pay
my bills by selling bugs my werewolf toddler catches by using his
practise hunting ability.

So I changed the game settings that my sims will be toddlers 14 days
instead of only 7 days. After they all learned to go to toilet themselves
I managed to teach them how to walk and talk. If your toddler hasn't
learned all these skills before his birthday you can't choose his traits.
And in this challenge it means losing some important points. So teach
all the needed skills to one child and after that move to another child.

This is one of the most common view of this challenge! After the first day your
adult sims energy bar won't at any point be any other colour that red or orange
before your toddlers become children...

Day 14 in the morning. All my toddlers can go to toilet, five of them can talk
and four of them can walk. Not going to get all the theoretical 12 trait points.
But I'm trying my best to get that fifth toddler to walk and get in total five trait points.
I didn't get any children taking away from me by the social workers though!
