I have a 12 year old boy who has only inherited parenting skills, as he has grown up they have increased and now he is an apprentice parent with no other skill.
That skill is going to be of no use until he is 18.

What task should I set him to be to begin with.
I know most will train in whatever skill you want but which is the most likely skill he will take to and not be one who annoys me constantly says NO or wanders off and I have to keep fetching him back!
Healing perhaps?

Healing, because he'll take care of the others!
Farming, because he'll feed all this futur kids!
Building, because he'll not be worried of housing!
Research, because he'll... learn!!

Does he had any "Likes/Dislikes"?

okay, just wait until he is fourteen. now, put him on the research table and he will learn. than, let him do farming. then let him do healing. then you put him building. then, you need to make all other males make parentng and make females pregnant. all males except him. then, let him do every skill but parenting. when he is elderly, put him breeding. he will not live long anymore, so soon when he dies, put children and they will get healing skills. it is very useful.

The chances of them constantly saying 'no' depend on the villager entirely! Liking or disliking learning can effect how likely they are to say "N0" when you're trying to teach them the skill early on. Liking or disliking work will effect how often they like to wander off-task. If he likes building, or science, or etc, that will be a good job for him. If he dislikes wood or lifting, building is a bad job, and so on.

It all depends on the villager. However, you can train him in healing by having him heal the sick even before age 14. I would save research or parenting for later in life, since building and farming involve a LOT of walking-distance, and walking long distances makes it very hard for the elderly to gain skills. They're just so slow!

Sadly this child was in the game I thought I had paused.
And when I went back to it, 36 hours or so later, he had grown up into an adult and his parenting skills were up, but still no other skills.
He and a whole load of other lazy kids were lying by the fire Bored!
About 15 of them.
All had no skills from parents or teaching.
All had their Dislike as Work!
And when I tried to make them do any work I got so fed up of the Word No, and I got fed up of putting them to work, I decided to start again.
I had lost well over 20 villagers in the time, including their chief.
And that is when I found out you can only have 50 headstones.
So they are all listed in the Roster but even though there is tons of room for more headstones they do not give you them.
This was the first VV3 game I began, and I chose nature.
But I sadly lost a few villagers early on as they starved as I had not found out about the Chief's skill at making food.
New game progressing well, and will soon actually play as I have about 500 food now. Should keep me going until my tree produces fruit.

Another point on that game, I do not know if it was a bug, or a Mac bug as it seems there is no Mac patch, we just are playing Version 1.0, the fire had 224 hours and ?minutes left to burn when I sent a villager to gather firewood and then checked to see how much time I had left!
Fortunately I had already got the ash key!!!

But it saved me having to remember the fire!!

Remember, if your game is paused but left running, aging continues. You need to pause, and quit to cease the aging process; switching tribes will do it, too. Just one of the quirks of this game.

LadyCFII's edit: This information is not correct.

Yes, I normally hit the space bar but now I am using the options button to be safe.
I rarely leave it running even on slow as I hate to miss things going on and I also want to get the collectibles.

In the game I started to replace the one with the apprentice parent, I have already got half of the feathers, shells and coral, and within the first 10 minutes of playing! Now I am in a 'dry' spell!
Poor kiddie will get sick soon from being zoomed around to keep looking.
The other kiddie is my Chief!

In the tribe it replaced I had only managed to get about half the collectables and finished the game and was just playing on to get the awards.

In my other tribe, the magic faction, I have completed 2 of the collections, the coral and the turtle-shells. And I was able to raise my population by 5 each time.
Again the actual game part is complete but I am going for the awards in particular the 90 year old plus.

(Sorry I do waffle a bit!!)

Lurkily, it is not true that aging continues if you pause the game and leave it running. You're misinterpreting a scenario from earlier games (and it's not true there, either, as long as you don't leave those games on the menu or options screen).

MickyTeddy, the current version of VV3 is 1.00.04 (the only way to determine the version is by looking at the game's menu screen, not by looking at file info). The only people who might still have v1.00.02 or v1.00.03 are people who bought the game in the first two weeks of release and purchased VV3 directly from LDW, and not another game portal (which all have v1.00.04). If you have an earlier version, you can see how to get 1.00.04 for Mac in this post.

Thanks. Sent you an e mail but I did not buy the game here.
And the place I got it have not upgraded the Mac version--yet!
Have spoken to them on several occasions.

Every game portal should have had v1.00.04. The earlier versions were available only from LDW before the game went to general release. I would be very suspicious of any game site that offered a version earlier than 1.00.04.
