Birthday Kid gets a Yoto player

Today my child turned 3, and her big gift this year is a Yoto Mini, as recommended by many folks in this group. We opened presents right after dinner, which is right before bedtime, so we've yet to see how she takes to it. The only concern I have right now is she likes to listen to it with headphones on, volume full blast. Any advice to help curb that would be great.

Pictured is her listening to the Very Hungry Caterpillar. I love the image of the caterpillar on the screen!
