Hi there… It might be a good idea to actually wander into an actual bookshop, such as Waterstones, and see what they suggest…
You may end up writing the book yourself… That is how people like Dale Carnegie started out. Maybe liase with playgroup staff, nursery teacher etc, to see if there is anything available to help.
Children are very perceptive, and when things are explained in a given way, can take on an amazing understanding of things around them. They have a unique perspective, and can themselves help us to ‘find our way through’ so to speak.
Welcome.
