Hello. I am writing a picture/narrative book which will also have beginner piano music in it. I'm aiming it at 4-6 yrs old. I am not certain whether I need to do a boy book and a girl book. I was thinking of aiming it at both boys and girls but wondered if that would end up appealing to neither. I'd be really grateful if any mums could advise me on what appeals and what does not appeal to girls and boys. I'm a grandma now and need to hear it from the grass roots. Thank you so much for your help.
