Peppa Pig - Playtime with Peppa Look, Find, and Listen - PI Kids Board book – June 18, 2019

My daughters currently are reading this book. However I wanted to check and see what age group should be reading it. I looked on the front and back numerous times but was unsuccessful in finding it. Why does it seem like they are purposely hiding the targets reading age? Unless I’m missing it the Amazon page doesn’t mention it and I don’t see it on the back.
