I did know someone who self published a children's book.
They were experts in marketing (albeit in another industry) so I thought they might have a chance.
The thing is, the industry they were from is far more modern. So the dynamics of marketing and distribution were way ahead in some aspects (the machinery of the supply chain) but regressive in one important way. The person had all the charm of an Apprentice candidate in the 'don't sack me, sir Alan, sack her' section of that ghastly reality show.
Even with their impressive sales skills, they were unable to get anyone to sell their children's book. (Although this particular person probably described it as a 'world class human start up reading solution'.)
The big chains order everything centrally, and the independents (which have all been royally screwed by the publishers, who offer bigger discounts to the chains, so they can sell cheaper and make a profit, and even higher discounts to Amazon, which I am convinced is the devil in corporate form. Amazon actually wants to own publishing and kill off the olde worlde publishers and yet they obligingly helped this monster to help itself to their territory.)
So it's near impossible to get anyone to take your book on.
Selling it online is harder still, because nobody has heard of you, and Cyberspace is a cold, soulless world. It's like outer space, only with less atmosphere.
Think about it. When was the last time you bought a book from a complete stranger online?
For some reasons, celebrities have more kudos than we uncelebrated people, so they have more chance of flogging books.
However, if you are thinking of writing a children's book for the sheer joy of having something you can share with loved ones, that is beautiful. Sales to complete strangers will be really hard though.
The books I loved reading to my daughter were varied.
At first, they are pretty simple, lyrically. Some were quite tactile, with about four words per page and lots of stuff to feel. The vivid colours and the images are as attention grabbing as the words.
That is deliberate because the young mind is developing. Synapses are being constructed and neural pathways laid down. They are processing information from all kinds of different sources and somehow piecing it together to make sense of it.
I remember one in a series called "That's not my Dinosaur"
The plot was so basic even I could follow it.
on the first page, there is a picture of a dinosaur (one of the large herbivores) with a raised slightly abrasive portion that kids were encouraged to feel.
The words on the pages said "That's not my dinosaur, its skin is too rough"
Reading to a child is more an activity, as they enjoy sitting with you, turning the page, feeling it, listening to your voice. I'm endlessly fascinated about how a child's brain processes all this complex input and somehow puts it together and works out the complexities of our language.
Lord knows how the young human brain makes sense of all this. But they do. They learn language from scratch.
It's a lot harder to write a children's book than people think. It takes genius to make things look easy.
Anyway, back to the self publisher.
He produced a professional looking book. But it was awful. That narrative was far too convoluted. Massively long sentences that would drive an IT salesman's eye off the page, let alone a young child.
When the book never took off, this person took it personally and got very bitter. Last I heard he was seen in reception of a do, angry and trollied, ranting at random people.
I think what I'm trying to say is.
Start simple with an audience of one and see how it goes from there.
It is worth going to a trade fair, if you can sneak in free, as it gives you a glimpse into the awful realities of book publishing and the people who inhabit that world.
