At this age children are aware and curious about the differences between the sexes. Often they just need the name of something and are happy with short, simple, truthful answers.
Reading them stories can be a good way of talking about different feelings and relationships.
Children may touch their genitals at this age. It’s very normal, they’re exploring their body. This is a good time to teach them what’s acceptable to do in public and private.
