Adoption

Adoption is an option in all games The Sims, The Sims 2, and The Sims 3. It allows a couple (opposite- or same-sex) or a single Sim to adopt a child.

Adoption process
In The Sims, Sim couples get random calls from adoption centers asking if they want to adopt a baby. The adoption center will not call a single Sim.

In The Sims 2 and The Sims 3. Sims can initiate the adoption of a child over the phone by calling the "Adoption Center" under the Service menu, but only if the Social Worker has not taken one of their kids. In The Sims 2, the household must have at least 3000 simoleons on hand (though adoption itself does not cost any money) and below 8 household members to adopt.

If the family is approved, the Social Worker will bring the new child the next day at 10 AM. To make sure someone is there to receive the child, it's best to call the day before a Sim's day off.

At 10 AM the Social Worker will arrive and the player will be asked which age they want the adopted child to be, a baby, toddler, or child. In The Sims 3, the player may also choose the sex of the child. This is the only option the player has when adopting. Not answering will give a child. If a baby who wasn't taken away by the social worker is being adopted, then the player gets to name him/her. The adopted child will have the last name of the Sim who made the call. (Mostly. In the sims 2, it may happen really rarely, and most likely because of a glitch, that the adopted baby/toddler/child has another last name than his/her parent(s).)

Families will not be allowed to adopt a child at all if the Social Worker has previously taken away a child in their household.

Adopting children taken by the Social Worker
Children in The Sims 2 and The Sims 3 who have been taken away from a family by a Social Worker are first in line to be adopted by another family.

When a child that was taken away from another family is adopted, their old parents and siblings will remain known to them but only as friends.

If one family loses their baby/toddler/child, then if another family makes a call then the youngster gets to live with that family (if the last family had a toddler, then the other family that makes the call has to select toddler, this is an obvious reason why.)

Adopting pets
In Unleashed, pets can be adopted on community lots in Old Town that have the Frisky Feline Promo Pen and/or the Fluffy Puppy Pet Bin. By default, these displays can be found in Pet Paradise, at 70 Elm Street. Players will be able to choose the gender of the pet, and to select from a number of breeds. Players can use custom pet skins, but a pet cannot be customized once it has been selected.

In The Sims 2: Pets, Sims can call the pet adoption service and adopt a kitten or puppy, or an adult cat or dog. If the call was made before 10 AM, the pet will arrive that day, otherwise it will arrive at 10 AM the next day. Sims can adopt adult cats and dogs on community lots that have the Cat-Crazy Pet Display and/or Doggonit Pet Display. Players can use one of the premade pet shops in the Lots and Houses bin, or can build their own. These displays allow players to access a streamlined version of Create a Pet. Regardless of whether a display shows a cat or a dog, it will allow the player to create either species. Of course, players can also go into CAS, create a cat or dog, and merge it into an existing (non-University) household.

For a Sim to be able to adopt a pet in Unleashed, the player must use the "Explore Old Town" option to call the cab to Old Town. If the Sim took a date to Old Town, the option to adopt will not appear. In Pets, a family can adopt a pet from a pet shop even if only one member travels to the shop.

In both games, Sims can adopt strays that wander onto their lot.
