That's until they find out that actually, it's the small things that count! Whether it's turning off the tap when brushing our teeth, or not wasting paper when drawing pictures, Dave and Greta show us that you're never too small to make a difference. A funny and reassuring story that's perfect for teaching little ones about the environment. A brightly coloured, rhyming picture book to read together at bedtime, again and again.
