To conceive a baby in Stardew Valley, a married couple must sleep in the same bed, with the wife having a Mermaid’s Pendant. After 14 in-game days, the wife will be pregnant.
Having a child in Stardew Valley adds a new layer of gameplay, as players must now care for their child and manage their family’s needs. Children can grow up and become playable characters, allowing players to experience the game from a different perspective. The addition of children to the game has been praised by players, as it adds a sense of realism and depth to the gameplay.
