In The Sims 4, if a Sim is pregnant the player can influence what gender the child will be. If the pregnant Sim eats carrots or listens to alternative music on the radio, the baby is more likely to be a boy. If the pregnant Sim eats strawberries or listens to pop music on the radio, the baby is more likely to be a girl.

If a Sim interacts with a certain tree, they will eventually be able to explore it. This will unlock a secret area called "Sylvain Glades".
