It's easy to help your child learn when you foster the interests they already have. They will be more likely to interact with you and their attention will be focused for longer.
Talking about a topic they already love will also let them know that you care about their interests and give your child a sense of security when they're with you.
Learning is fun when it's with someone you care about!
