I found these Lego ads while browsing a while back. Not even 100% sure they’re genuine or if they were used but they’re great. Have a look -
Children are remarkable at interpreting symbols. These Lego ads are absolutely spot-on. Children can look at a few blocks and see a dinosaur. And, even if there is nothing really there to make sense of, a child’s mind will try. So in a complex pattern, they could see countless images, each child seeing something different.
A child seems to want to put a form to abstractions.
This is important to bear in mind when creating something for young children. What you consider art could be open to far too much interpretation to a child. Your hair design could have some children seeing snakes. Your background design could have children trying to make sense out of a wood pattern rather than watching the characters.
Thinking in simple symbols is very important.
This is part of why I think Peppa Pig is such a hit. Look at how clear the forms are -
And yet, even here, my daughter once asked me why Mummy Pig has spiders on her eyes.
