There's a children's bookshop opening next door to Hamlet's on the Hornsey Road. Self-promotion: http://thehornseyroad.blogspot.co.uk/2012/06/were-getting-bookshop-squeee.html
And another children's bookshop opening in the old Sally Bourne shop next to The Haberdashery in Crouch End!
Hope both are as good as the completely fabulous award winning one in Muswell Hill.
Children seem to mostly like The Gruffalo, Octonauts, Peppa Pig, anything about pottys and poo, David Walliams (much better than you'd think), Mr Gum, Roald Dahl, anything with Pirates and the Rainbow Fairies. Parents like all the things you've listed in your blog so we sell lots of all of that too.
