When a baby is born, they can grow up to like different things like colors, toys, and people. Some babies grow up to like boys, some grow up to like girls, and some grow up to like both boys and girls. This is called sexual orientation, which means who a person is attracted to.
The environment around a baby can also have an effect on their sexual orientation. For example, if a baby grows up with only boys around, they might develop a preference for boys when they grow up. However, this is not always the case and many people have a different sexual orientation than what their environment might suggest.
It's important to remember that there is no right or wrong sexual orientation, and everyone should be accepted and loved for who they are.
