As your toddler reaches 21 months, they’re beginning to exhibit distinct preferences in toys, games, and playmates, marking a significant step in their individuality. While some children may lean towards traditional gender preferences—such as girls favoring dolls and boys gravitating towards cars—others may surprise you. For instance, a girl might enjoy digging in the dirt while a boy might prefer hosting tea parties. Whatever your child’s interests—be it dinosaurs or drawing—embrace them and avoid imposing limitations. It’s important to remember that today’s obsessions may not define their future interests; toddlers are known for exploring various phases throughout their development.
