How to unlock the Prepared For The Future achievement in Fallout Shelter - Definitive Guide
In order to, erm, grow the population from the, um, inside out, you need to place a male and a female into living quarters. Charisma has a massive effect on this, particularly the time it takes for the two to decide to get together. First they talk, then they dance, then they run into the back of the room... he runs out happy, she limps out, holding her back and wearing a yellow shirt. She is now pregnant.
You'll need to upgrade your living quarters, now.
A key to making this faster is to have both male and female max out their charisma. Have each wear clothing that increases charisma, and it'll go faster.
Pregnant women still use any gear you give them, so any clothing perks they have will still apply. This is important in maximizing efficiency. However, you'll want to consider taking good weapons away from them while they're pregnant. Pregnant women run away from fights.
After several hours, you'll be told that a baby is coming. Click on the little green baby head icon, and the baby will then join the population, and she will revert to whatever gear she is wearing. If you are working to grow the population quickly, you can again place her in quarters with a man, and the circle of life repeats.
Of note: babies will not be born when your vault is full (they stay pregnant), so either dwellers will need to die or be exiled first.
I have a guide explaining this process if you need just a tad bit more detail:
Things to note about pregnant dwellers and kids:
You can put a pregnant woman back to work but not out to the wasteland. In an emergency she will run away, she will not fight while pregnant. So outfits and weapons are worthless on pregnant dwellers. You cannot make babies with dwellers from the same family...that would just be creepy anyway. You can make babies repeatedly with the same two dwellers. The woman will give birth to a dweller child, which will add to your population. They too are worthless in a fight. They cannot be equipped with gear until they mature to adults after 3 hours. When born they have a mixture of the parents stats. Higher stats on parent means higher stats for the children. Higher CHARISMA on the parent will speed up the time it takes before a dweller becomes pregnant
*thanks to BOngAAA for the 3 hour info
To unlock this achievement, you need to first have at least 1 male and female dweller in your vault, then you simply place the 2 of them together in the Living Quarters and give them some alone time. After a few minutes the female will become pregnant and then after 3 hours real time, you can select the mother, who will have a baby icon over her head, and then the baby will be born. Obviously this achievement will be faster if you have more than 1 female but it can be done with just one pair. It is worth noting that there is no incest in the vault, so if you try to put parent and child or grandparent and grandchild in the same room, nothing will happen. After 25 babies have been born, this achievement will unlock.
To make a baby, you need to assign a male Dweller and a female Dweller to the same Living Quarters. They will start to talk, then dance and eventually make babies. The amount of time to get the female pregnant will depend on the Charisma stats of the two Dwellers concerned. Once the female is pregnant, you will need to wait/skip 3 hours until you can click on them and add another Dweller to your Vault. You will need to wait/skip 3 other hours in order to use the Dweller, as children can't do anything in your Vault.
You can have multiple couples in the same Living quarter, as long as it's a merged room, you can make babies with different couples or make 25 babies with the same couple, it's up to you. Note that you cannot make babies with dwellers of the same family. You will know if this has happened, if you assign them to the Living Quarters they will talk about how it feels good to be with their family. There is certain pet that gives a 2x chance of a female Dweller having twins, if you want to speed up this trophy or increasing the population a bit quicker.
The birth time of a child is 3 hours, +3 hours until he becomes an adult. If you want to develop faster, it is important to put the birth of a child on the conveyor belt, but do not forget to monitor other resources.
then repeat.
incest is prohibited (you can’t mate with your own children - they usually have their father’s last name), but no one is stopping you from pairing up all the former mothers and their daughters with the next alpha M to whom you will throw.
I understand that if there are two namesakes in the room, then the flirting process will not work. in general, if a male stands alone and does not flirt, then he will simply exchange women for others, or maybe even change the male.
