Engaging, lots of interest and lots of flaps with extra information or images to engage. I would say that this book would be suitable for older children too as they could read this independently and the language is detailed and doesn’t patronise.
Having said that, the board book element makes it accessible for younger ones and the illustrations are engaging even for little ones (esp if, like Bud, they are vehicle/ engineering minded at the moment)
We would get this out again and I’m sort of sad to see this one go back. We would consider buying this and would recommend to others.
